Hi: Remember that I somewhat enthusiastically wrote that a VB3 program called "Watchtower Library 1999" now works with wine-010508? Well, [un]fortunately it is broken with again with the wine-010510 tar ball. (Thank you, Kin Lau for pointing this out to me by e-mail.) Description: The main program window of WTLIB99 is just a small bar with buttons and a menu on top of the buttons.

Hello UseRs: Excuses for my english. I have a dataset with 65000 records and I'd like to make a summary where I can view all the values (with the number of times that it repeats) that there are each column of my dataset. I tried with summary( ), str( ), but nothing gives me the result that I am loking for. Thank you very much.

Dear listers, I'm having a bad R day. I just can't think of the vectorized equivalent of: for (ii in 1:n) aa[ii] = bb[ii,cc[ii]] Any suggestion received with embarrassment and gratitude Simon Gatehouse CSIRO Exploration and Mining, Newbigin Close off Julius Ave North Ryde, NSW Mail: PO Box 136, North Ryde NSW 1670, Australia

Hi, is there a way to reference to a data object without copying it? For example I have a huge matrix called dist and I want two objects obj1 and obj2 to have a memeber dist that points to the matrix, but I don't want, for memory reasons, to copy the matrix twice. As far as I understand the following code will generate three copies of my data: dist <- some_code_that_generates_data

Hello, I wonder if someone could help me with the following: I have generated 10 000 values from rnorm and now I want to randomly replace 500 of those with NA. The problem is that values indexed between 6-10,16-20,26-30.... only should be considered for replacement. Any suggestions?

I have a data frame (df) with colums x, y and z. e.g. df <- data.frame(x = sample(4), y = sample(4), z = sample(4)) I can extract column z by: df$z or df[3] I can also extract columns x,y by: df[1:2] or by df[-3]. Is it possible to extract x,y columns in a "symbolic" fashion i.e. by equivalent of df[-z] (which is illegal) ??? Or alternativeley, is there an equivalent of

My search site, http://finzi.psych.upenn.edu, has had several problems recently, all my fault, for which I apologize. But it now seems to be running reliably, on a new computer that is much faster than the old one. It uses htdig to permit search of the Rhelp mailing list, R documents, R functions, and various combinations of these. Search has several options, including Boolean search (with AND,

Dear R Help, I am trying to create a boolean vector that is TRUE whenever a particular value occurs in a numeric vector, and FALSE otherwise. For example, suppose that > y <- c(5, 2, 4, 3, 1) > y [1] 5 2 4 3 1 and suppose that I want to find where 3 occurs in y. Then, the following yields the solution: > y == 3 [1] FALSE FALSE FALSE TRUE FALSE My problem arises when the

Dear all! After hours of trying around, I gave up: I have a 2-dimensional array, and I know how to split it into its rows and how to get the mean for every row using 'sapply'. But what I want is to calculate the mean over the first n rows, and then the second n rows, etc., so that I get a vector like: v == mean1(row 1:5), mean2(row6:10),... (trivial, you might say. I find it rather

Hi, I'm trying to subset a list which contains variable length vectors. What I want to do is extract (eg.) the 3rd item in each vector (with length >= 3). At the moment I'm using sapply(list.of.vectors, function(x) {x[3]}). The problem with this is that sapply returns a list of the same length of list.of.vectors so I end up with a whole lot of null entries from those vectors

Hello, I am a beginner in R programming and recently heard about this mailing list. Currently, I am trapped into a simple problem for which I just can't find a solution. I have a huge dataset (~81,000 observations) that has been analyzed and the final result is in the form of 0 and 1(one column). I need to write a code to process this column in a little complicated way. These 81,000
