in R , when i use "print", i can see all the values, but how can i save this as a vector
for example, in for loop,
for (i in 1:10), i want the value of A , when i= 1,2,3,4..... but if i use the x=A, it only have the final value of A which is the value when i = 10. so , how can i save the vaule in print(A)..
BY THE WAY , I use ...

Hello, I am using the twitteR package in R to update my twitter status with results from analysis. The static tweet function works:
library(twitteR)
sess = initSession('username','password')
tweet = tweet('I am a tweet', sess)
However, when I add a variable to display some specific results I get an error.

I have a data.frame in R. It contains a lot of data : gene expression levels from many (125) arrays. I'd like the data in Python, due mostly to my incompetence in R and the fact that this was supposed to be a 30 minute job.
I would like the following code to work. To understand this code, know that the variable path contains the full pa...
Hi,
Is there a way to call an R-Script within C-Code?
I did find the R Api for C (chaper 6. of the 'Writing R Extensions' manual), but as far as I understood this does "only" allow to call the C-Implementation of R. Of cause I could call the R-Script via shell, but that's no solution for me, since this does not allow proper passing of...
Hi useRs,
I am looking for a solution that allows me to keep a track of a multitude of R scripts that I create for various projects and purposes. Some scripts are easily tracked to specific projects, whereas others are "convenience" functions created to serve a set of tasks.
Is there a way I can create a central DB and query it to find ...
I came across this in the following context from B. Pfaff's "Analysis of Integrated and Cointegrated Time Series in R"

is there any command to find the standard error of the mean in R

a = matrix(1:25,5,5)
B = capture.output(for (X in 1:5){
A = c(min(a[,X]),quantile(a[,X],0.25),median(a[,X]),quantile(a[,X],0.75),max(a[,X]),mean(a[,X]),sd(a[,X])/m^(1/2),var(a[,X]))
cat(A,"\n")
})

I am building a bar chart for which bars suffice as indications of horizontal (x) placement, so I'd like to avoid drawing the superfluous vertical gridlines.
I understand how to style the minor and major gridlines in opts(), but I can't for the life of me figure out how to suppress just the vertical gridlines.

Has anyone connected the R package to QuickBooks? I know there is an ODBC driver than can be bought. Just wondering if anyone has already gone down this road.
Any insight will be much appreciated!

R has a useful function pairs that provides nice matrix of plots of pairwise connections between variables in a data set. The resulting plot looks similar to the following figure, copied from this blog post:

I heard R is the "de facto" language amongst statistical software developers, and I'm giving it a try. I already know the basics, but it still looks "weird" to me (a C developer). I think it would be very useful to see a working example to see how a real R program is built.
I thought that an R solution for any of the mlbench problems wou...
I'm creating a GUI in R using gWidgets (more specifically gWidgetstcltk). I'd like to know how to update the contents of selection-type widgets, such as gdroplist and gtable. I currently have a rather hackish method of deleting the widget and re-creating it. I'm sure there's a better way.
This simple example displays all the variable...
