Hi, Until recently I was using the knncat classifier function of knncat on an old computer (2.12, Mac OS X 10.4), and everything worked great. However, now that I have updated to R 2.14.1 (on Mac OS X 10.7), knncat seems broken. Problems: 1. It seems to output verbose output by default, and regardless of whether I put 0 or 1 into the verbose option. 2. It seems to just predict

I use knncat to make a predictive model and get misclass rate > knncat.m<-knncat(training.new,k=c(10,20),classcol=5) > knncat.m Training set misclass rate: 36.88% then I try to calculate prediction accuracy by the following: > pr.knncat.train <- predict (knncat.m,training.new,training.new,train.classcol=5,newdata.classcol=5) > tb.knncat.train <-table (pr.knncat.train,

Hi: I've searched the archives and the Internet for hours but have yet to find a way to do stacked area plots (like the kind in Excel) in R. I think that polygon may work but it would require a bit of manipulation of my data. I was hoping for an easier way. An example of what I'm trying to do can be found here: http://jcharts.sourceforge.net/samples/stackedArea.html Thanks, Josip

Dear R-Helpers: I'm having a problem getting dates into the correct format. I have a data frame, which is based on a .csv file that I imported into R via read.table. R has converted my date variables to factors; when I use the as.Date command, most of the values are converted "correctly" (and by this I guess I mean converted "as I wish them to be") but some have not been.

Hi there noticed a strange thing in asterisk 1.6.2x 1.6.1x after one of the clients sends bye asterisk first sends invite to other side then after 200 ok it sends bye I am not sure but that could be some missconfiguration issue or a bug? so it's like this: side A sends bye to asterisk, asterisk responds with 200 OK to side A, then it sends INVITE to side B, expects 200 OK

Dear R Help-Listers: I have a problem that seems like it should have a simple solution, but I've spent hours on it (and searching the r-help archives) to no avail. What I'd like to do is to generate a new variable within a data frame, the values of which are dependent upon the values of an existing variable within that data frame. Assume that I have the following data:

Hello: As someone making the move from STATA to R, I'm finding it difficult at times to perform basic tasks in R, so forgive me if I've missed an obvious and easily obtained solution to my problem. I've searched the help guides and the archives and have not been able to find a solution that works. I have a data frame with thousands of observations that looks something like this:
