Thanks a lot for all of you that have reply me about opening and ending R workspaces in BATCH mode. However replies were a king general and I?m afraid I could not take the entire message from them. Therefore I chose to expose here a representative fraction of my work. I have 50 Rdata files (F1,F2,F3,F4, ,F50) with objects inside. I need to: open F1: - perform some simple operations

Dear Rusers, I am still an unexperienced builder of functions and loops, so my question is very basic: Is it possible to introduce a second variable (j) into my loop. To examplify: # This works fine: fn <- function (x) {if (x>46 & x<52) 1 else 0} res <-NULL for (i in 40:60) res <-c(res,fn(i)) res # But here, there is an error in the "for" expression: fn <-

It seems that you have load the "survival" package date.mdy is a function from this one. In this function the "origin" of the time is the first day of 1970 in the base package the origin is the first day of 1960 it's very curious...

I am trying to make a graph with 4 scatter matrixes plots and couldn't do it. While trying to find a solution for this I also came across the idea of giving different values to the same argument for each of the lower and upper function but couldn't do it. (Examplified below with the col argument). The first problem of plotting 4 scatter matrixes in a graph is a problem of real

...nd output the likelihood using the sample data (imported within the function). In order to make R optimizers to work I, apparently, should write a function that uses the parameters and the sample data as input and outputs the likelihood. Is it correct? Could someone reply with an example code which examplifies the type of function I should write and the syntax to optimize? Alternatively, could anyone suggest a good MLE tutorial and package?

Hi. WISHLIST: Regardless on console, I'd like to be able to timeout a call to readline()/file("stdin", blocking=TRUE) via setTimeLimit. OBSERVATION: On Windows Rterm as well as plain R on Linux, setTimeLimit() does not momentarily interrupt from stdin, but only after hitting RETURN. A few examples: timeout00 <- function() { setTimeLimit(elapsed=5); Sys.sleep(10); }

Thanks for pointing me out "aggregate", that works fine! There is one complication though: I have mixed types (numerical and character), So the matrix is of the form: A 1.0 200 ID1 A 3.0 800 ID1 A 2.0 200 ID1 B 0.5 20 ID2 B 0.9 50 ID2 C 5.0 70 ID1 One letter always has the same ID but one ID can be shared by many letters (like ID1) I just want to keep track of the ID, and get
