data.frame to matrix
Dear Gustavo, To fill in other list members, this is occurring with code written to augment the Rcmdr package. The problem is that .numeric is a vector of names of numeric variables in the "active data set" (data frame) maintained by Rcmdr, it is not itself a data frame. Consequently, your varstemp is also a vector of names, which could be used to index the active data set, whose name is stored in .activeDataSet. I hope that this helps, John On Mon, 9 Feb 2004 17:47:36 -0300

Hello all, I've had trouble converting a data.frame to a matrix (numeric) using either data.matrix() and as.matrix(). After executing one of those I end up with another data.frame with only the first column of the original data.frame. I use a window (tcltk) to let the user choose the columns he wants and then I retrieve them using the following: varstemp <- .numeric[as.numeric(tkcurselection(subgroupsBox)) + 1] where ".numeric" is the original (complete) data.frame. Any ideas why is this happening? I'm using R1.8.1 in WinXP by the way. Thanks.
