Hello, I am a new user. I would like to know if it is possible with R to fix the position of ticks. for example for my plot I obtained automatically the positions 200,400,600,800 and 1000 on x axis and so a scale of 200 But I would like to obtain 100,200,300,400,500,600,700,800,900,100 so a scale of 100. Which fonction can help me to do so? thank you meriema

Hello I have used recently the kolmogorov smirnov test, which is a test of normality. This test is named ks.test() in ctest library of R.

Dear R-community, not to re-invent the wheel I wonder if someone of you has ever written a function to compute the GHK smooth recursive simulator to estimate multivariate normal probabilities.

Hello, Splus contains the function intbin(x,l). This function allows to make a conversion from an integer x to a binary of length l. for example intbin(3,2) returns 11 intbin(3,3) returns 011 Do you know how to do it in R ? Thank you meriema

Dear helpeRs, a colleague of mine would like to give R a try. He uses econometric models which typically involve a large number of variables, esp. time series. Having no experience with handling very large data sets myself I turn to you. 1. Could you please describe your experiences to cope with these situations? 2. What kind of difficulties will he have to face? Are there special

Dear HelpeRs, I'm very fond of Sweave and I use it as often as possible. It'a a pity I can't use it for larger projects or can I? For instance suppose I have three files file1.rnw, file2.rnw and file3.rnw with Sweave code. Working on file2.rnw I whould like to exclude file1.rnw and file3.rnw temporarily and joining all of them later. This amounts to a mechanism similar to using

Dear HelpeRs, I wonder if anyone knows of ways to read EViews file types.

I have some data which I would like to display with dotchart. The labels are very long, so the chart becomes too small. Setting cex=0.7 seems to be a good compromise, but the gap between the text and the chart still is too large. I did not find a "gap" parameter in the description of dotchart... Thanks for any help.
