Hi All, I'm new with R; this is a basic question. I was given a matrix I of (nrow, ncol), I would like to create another matrix A with some data in the matrix I, say [1,4] (row 1, column 4) to [271,19000] (row 271, column 19000). How do I do this? Please help. Thank you very much. --mc [[alternative HTML version deleted]]

Hello, I received the following warning when running chi-square; n Is there a way to catch the 'error' code of 'warning' after run chisq.test(x)? n What does this error mean? Thank you for your help. [[alternative HTML version deleted]]

Hello, Newbie question and hope you can help . I have two vector V1 and V2, where length(V2) = length of (V1) * 2; length(V1) ~ 16,000. For each member in V1, I need to compare 2 element of V2 for equality i.e. for (I in 1:length (V1)) { if ( v2[i] == v1[i] & v2[i+1]==v1[i] ){ statement_1 statement_2 . } } This for-loop is too slow

Hi, I place a t.test in a loop and would like to continue to process the loop even when t.test encounter error. How do I do that? For example, in one iteration, the data is completely constant and t.test gives error, the entire program terminates. I would like to write the information out to a file, and the loop should continue. Thanks My D. Coyne [[alternative HTML version

R-newbie question I have 2 matrices (a) P1 has only one column of 32K rows (b) PC has 2 column {P, C} of 3200 rows Every values in P1 matches with a value in PC[,p] (column p). I would like to use Which to search for all value in P1 that matchex PC[,p] and get the PC[,c]. However because P1 and PC does not have the same number of rows, I got lots of 'NA'. Thanks for your

Hello, I would like to run a series of chisq.test() and store results (x-square, df, p-value) in a matrix for further analysis, but don't know how to do such. Currently I run the command line for each set of data at a time and it is time consuming. Thank you for your help. --My Coyne [[alternative HTML version deleted]]

I'm ordering "The R Book" and hope to learn a lot more about R. In a meantime, I have a matrix of digits and I would like to look for a column that contains zeroes and remove the entire column from the matrix. I can write a piece of R code to do that (and it works); however, I think the R-experts have more tricks to do such a 'simple' thing. Many thanks in advance.
