[R] Automating R script with Windows 7

Hi R-users, I am trying to automate the daily running of a simple R script from Windows 7. From previous posts, I understand that this needs to be done with the task scheduler. I can schedule my laptop to automatically open R at a certain time, but not to execute a script. Secondary question:

Re: [R] Automating R script with Windows 7

Hey Jim, Thanks for the help. It took me a little bit of research but I got your solution to work. For everybody who has the same problem (1) remember to use the abbreviated names (no space) in folder paths: ex: 'C:\PROGRA~1\R\R-2.11.1\bin\RScript.exe' (2) put the folder with the R script to

Re: [R] Automating R script with Windows 7

Hi Jim, Please disregard my earlier post -- I have done some research and realized the space between after program was the the issue. I can now open RScript.exe from the command prompt using the abbreviated form: C:\PROGRA~1\R\R-2.11.1\bin\RScript.exe From your earlier post, I understand the

[R] Saving run time in loop

Hi r users, I am trying to compute the moving variance of a large matrix. I now use a loop but I am looking for a faster solution. Here is a sample of the code. Source= matrix(rnorm(400),ncol=100) variances= matrix(rep(NA,4*100),ncol=100) for (i in 1:80)

[R] Right digits of a floating number

Hi all, I am dealing with very large numbers but I am only interested in their last digits. 244^244 [1] Inf As far as I can tell, the largest number R can take has 308 digits (1+E308). Is there a way I could see the last digits only of 244^244? Many thanks for your help. Vincent Deluard,

[R] Anybody has experience with plotlm3d function and can help me?

Hi Duncan, I am trying to use the plotlm3d function which I believe was written by John Fox and later modified by Jose Claudio Faria and Duncan Murdoch. It is a great way to plot data points in a 3D environment but I do not see how to customize the size of the axes. I want to plot the

Dear Phil, You helped me with a request to rand matrix columns by deciles two weeks ago. This really un-blocked me on this project but I found a little bug. As in before, my data is in a matrix: madebt[1:16,1:2] X4.19.2010 X4.16.2010 [1,] 26.61197531 26.58950617 [2,] 5.72765432

[R] Evaluating matrices without using loops

Hi R users, I am trying to set the values of elements of one matrix based on the values of elements of another matrix. Say I have 2 matrices, y and z. y = matrix(rnorm(35), ncol=5) z = matrix(rep(0,35), ncol=5) I want z[i,j] to take a value of y[i,j] when y[i,j] is greater than 0, and zero
