Hello, I've been learning ggplot in the last few weeks. Generally, I'm getting things done (slowly though), but now I'm stuck. I created the following facetted plot: http://dl.dropbox.com/u/7752237/example_bad_y_scales.pdf Faceting is done by pl <- pl + facet_wrap(~sci_name,ncol=1,scale="free") The Problem: Numbers on the y-scale d...
I have a large CSV with the results of a medical survey from different locations (the location is a factor present in the data). As some analyses are specific to a location and for convenience, I'd like to extract subframes with the rows only from those locations. It happens that the location is the very first field so yes, I could do it...
I'm wondering if the following is possible. I have a survey with 100+ questions, all categorical, collected in 4 locations. All questions are labeled q1, q2 and so on. Let's say there are 100 for simplicity. I can visually compare the results of a particular question across locations with: library (lattice); histogram(~ q75 | location...

Dear all, I try to find out if x11 census type filtering is possible with R. I am pretty sure it is, but if I google or use ??x11 I only get information about the graphical device X11. Can anyone point me to some time series package respectively a function (e.g. within zoo or standard ts) that does it? thx in advance! ...
I am using a the RSQLite library in R in to manage a data set that is too large for RAM. For each regression I query the database to retrieve a fiscal year at a time. Now I have the fiscal year hard-coded: data.annual <- dbGetQuery(db, "SELECT * FROM annual WHERE fyear==2008") I would like to make the fiscal year (2008 above) to make ...

Is there a way to programmatically find the path of an R script inside the script itself? I am asking this because I have several scripts that use RGtk2 and load a GUI from a .glade file. In these scripts I am obliged to put a setwd("path/to/the/script") instruction at the beginning, otherwise the .glade file (which is in the same dire...
I have two data.frames. For examples sake let's say they look like this: df1 <- data.frame(x=rep(letters[1:26], 16)) df2 <- data.frame(y=letters[1:4]) What I would like to do is subset 'df1' to contain the rows whose first column value matches any value within the first column of 'df2'. Now, I've tried: subset(df1, df1$x == df2$y)...
Dear SOers, I am writing my thesis in LaTeX and because things got a bit long for my taste, I had split it into several files. Let's call them thesis.tex, intro.tex, mat_n_met.tex, rslts.tex and discsn.tex. I have linked intro.tex, mat_n_met.tex, rslts.tex and discsn.tex through thesis.tex with \include{intro} (and so on...). I have als...
The labels on the x-axis are defaulting to scientific notation no matter how small cex.axis is. How can I override scientific notation to get the labels to print out as specified? Here is the code (UNIT here is 0.0105): plot( xm,yv ,log="xy",ylim=c(0.1,20)/UNIT, xlim=c(0.004,20)*UNIT,xlab="Dose",xaxt="n",ylab="Amount",type="n") ax...
I am an R newbie and had a question. I am trying to place some text into an R plot. Here's some code using the brightness dataset in the UsingR package. library(UsingR) brightness MyMean <- mean(brightness) MyMedian <- median(brightness) MySd <- sd(brightness) hist(brightness, breaks=35, main="This is a Histogr...
Is it possible in R to protect function names (or variables in general) so that they cannot be overwritten. I recently spotted that this can be a problem when creating a data frame with the name "new", which masked a function used by lmer and thus stopped it working. (Recovery is easy once you know what the problem is, here "rm(new)" d...
I am building an user input interface in R. onload of the program, I would like like to ask the user what their preferences are according to a set of 6 fields. This will then be used as a comparison tool for the rest of the program. e.g., >ThisProgram >"Hello, on a scale of 1 to 10, how much would you say you rate the outdoors in y...
I have a bunch of histograms to plot on data that is still coming. As the sample sizes vary, in order to compare them I need to plot the histograms with percentages not counts. qplot (field, data=mydata, geom="histogram", binwidth=10) the above qplot displays the counts. The density option is not applicable as it divides the counts wi...
Say, I am using facet_grid() in ggplot2 to obtain 2 histograms. Now I want to superimpose these histograms with Poisson curves (having different means for the 2 histogram plots/grids) and a second curve of another distribution (for which I want to manually provide the probability function of values). How can this be done? constructing ...
Hello.... So I have a data frame in R that contains integers, NA's, and a random assortment of strings inside the cells. Only one data type per cell. What I'm wondering is how to change all of the cells that contain strings into NA. Any idea how I could do this? ...
I'm using R under Windows XP. It picked up the environmental variable HOME from windows which is > Sys.getenv("R_USER") R_USER "H:" However, how can I use that variable quickly in a file name?
