Howto Superimpose Multiple Density Curves Into One Plot in R

I have a data that looks like this. And I intend to create multiple density curve into one plot, where each curve correspond to the unique ID. I tried to use "sm" package, with this code, but without success. library(sm) dat <- read.table("mydat.txt"); plotfn <- ("~/Desktop/flowgram_superimposed.pdf"); pdf(plotfn); sm.density.compare...

Generate stochastic random deviates from a density object with R

I have a density object dd created like this: x1 <- rnorm(1000) x2 <- rnorm(1000, 3, 2) x <- rbind(x1, x2) dd <- density(x) plot(dd) Which produces this very non-Gaussian distribution: I would ultimately like to get random deviates from this distribution similar to how rnorm gets deviates from a normal distribution. The way I ...

Plotting predefined density functions using ggplot and R

I have three data sets of different lengths and I would like to plot density functions of all three on the same plot. This is straight forward with base graphics: n <- c(rnorm(10000), rnorm(10000)) a <- c(rnorm(10001), rnorm(10001, 0, 2)) p <- c(rnorm(10002), rnorm(10002, 2, .5)) plot(density(n)) lines(density(a)) lines(density(p)) W...

Heatmap (density map) on GWT

I want to creata a heatmap (density map) on images. The examples like the one in http://www.heatmapapi.com/Sample%5FGoogle.aspx are good examples of what I try to do. Is there a GWT way of achieving this? Or any good (flash or js) solution you can suggest (other then the ones mentioned http://stackoverflow.com/questions/357721/heatmap-t...

BitmapDrawable with unexpected size in Android 2.0.1 WVGA854

I want to display a 480x320 JPEG file stored in the SD card in Android 2.0.1 with WVGA854 skin and 240 lcd density (Motorola Droid). However, when I create a BitmapDrawable through Drawable.createFromPath(), the resulting BitmapDrawable has the following values: mBitmapWidth = 320 mBitmapHeight = 213 mTargetDensity = 160 The manife...

How to make ImageButton in Android automatically scale based on screen density?

I have an image put on an ImageButton, which looks good on a mdpi (medium-dpi) screen. However, when the device has a hdpi (high-dpi) screen, the image is still pixel-by-pixel accurate, which look small on the device screen. How do I make such that the image (and therefore the ImageButton) scaled based on the density-independent pixels...

Load image in device independent and screen independent fashion into a layout view using 1.6 SDK

I'm having trouble getting an asset image to scale up when I load it. The new call to BitmapDrawable(Resources, BitmapDrawable) is not available on 1.6 SDK. Is there a workaround to load the BitmapDrawable the old way and then somehow manipulate it? I have tried calling setTargetDensity() to no avail. My code (which doesn't scale proper...

Determining image sizes for multiple android screen sizes/densities

I've been reviewing the Supporting Multiple Screens documentation on the Android and I just need some additional clarification... It's my understanding that designing three unique interfaces (ldpi, mdpi, and hdpi) would be the best way to go about supporting all the potential android screens with minimal scaling/distortion. Yes, I kno...

9 patch row background appears irregularly in Android

I'm using the following 9 patch image as the row background in a list view. (the image is right above this line, in case you missed it) I've placed this image in drawable-hdpi. When I run the app in a high density device, the grey border appears only while scrolling, and disappears when the list view is still. Why is this? The goal ...

How to plot a set of densities in 3D using R?

Hi! I need to plot, in 3D, a set of densities associated to a time series. More precisely, I would like to be able in R to build an image close to this example This image is taken from [1]. The transparency plays an important role as let us see the trajectory of the "measures" in the x-y plane. Any help will be greatly appreciated...

Android - How much space does a TextView take

How much space does a TextView take? When I declare a TextView, is it possible to calculate how much space (height and width) it is going to take when actually rendered on the phone? I have noticed that based on the different screen sizes of phones (or density), the TextView is rendered accordingly. I want to be able to calculate the e...

Android - Padding in different phones

Say I add a linear layout with top padding of 20. Does it mean that the layout is rendered with 20 pixels of padding in all phones? Or does it scale according to the height/width/density of the phone? Thanks Chris ...

Android Webview Zoom Density

I would like to set the zoomlevel on my WebView (WebChromeClient). According to the API WebSettings holds a static method ZoomDensity that should do the trick but I just can't make it work.

I added the following to my manifest: <supports-screens android:smallScreens="false" android:normalScreens="true" ...

[R] Shading a kernel density plot between two points.

I frequently use kernel density plots to illustrate distributions. These are easy and fast to create in R like so: set.seed(1) draws <- rnorm(100)^2 dens <- density(draws) plot(dens) #or in one line like this: plot(density(rnorm(100)^2)) Which gives me this nice little PDF: I'd like to shade the area under the PDF from the 75th to ...

I'm trying to render custom buttons in Android. However, I'm having issues getting my bitmaps to render without scaling. I have a few constraints that are forcing me to forgo a few possible solutions. First, my bitmaps are being generated using a byte array through BitmapFactory; which I'm passing in bitmap options that specify inScaled=...
