After searching in R- Introduction, FAQ, help... I don't understand this: I write a function in a file (.R): tt <- function(mc) { date() mc<-read.csv2("machines.txt",na.strings="") date() } I source it in R and I type tt(). The answer is > tt() [1] "Mon Aug 14 11:18:25 2000" > The instructions following the first "date()" are ignored. Why?

And then collect my new datas. But I don't know how doing this. Perhaps a linear regression ?? See .jpeg foto. Thanks for any help it will be given.

Hi all, I want to use a fourth plot on a page as a "map" of how to interpret the previous three plots - so the x axes are all the same but I want the y axis on the fourth plot to have no graduations or numbers - is this possible?

Hi people, I have made some progress trying to work out how to solve this problem but I have got a bit stuck - sorry if this turns out to be a simple exercise . .

Hi all, I hope someone can give me some quick pointers - it would take me ages to work this out from scratch - I want to: - From an array - 32 cols x 1000 rows of small floats - Produce a second array from the first where the all numbers have an abs fn applied to them (to get rid of the neg numbers) - Produce a third array from the second where all numbers less than 0.0005 are converted to
