...to run a discriminate analysis on a data set, but have no idea how to go about this in R. I have attempted to locate info in the manuals, but may not be consulting the right sections or documents.

...ction. I'm imagining something like by(df, pchCode, function(x) plot(V1, V2, pch=pchCode)) What I don't know how to code is: 1. getting the pch to be defined by the pchCode 2. specifying that par(new=TRUE) within the by command.

Hello, Can anyone offer any insight on graphing classification dendrograms with the nodes marked? plot(tree()) produces a nice tree structure but there's no acccompanying text. Thanks, D S.

.... I tried a loop: > for(i in ls(pattern="csv")) +write.table(i, file=i, sep=",", quote=F) That, of course, wrote out a bunch of files that contained x 1, n002.csv Or the like. How can I get i in the loop above to be an object instead of a string? Thanks S.

...attribute must be the same length as the vector I have written a complicated analysis algorithm to examine a large dataset. The analysis appears to run on small numbers of tokens, say 10.

Dear R-List, How can one look up the row/column number for a given value in a matrix or data.frame? For example in a matrix that contains only unique values for in [,1] how can I find value x in [,1] and report its row number? TIA, David S.
