...want to use lattice, because I have hundreds of plots. So, to keep it simple, let's say I am plotting 3 series of boxplots like, boxplot(data1~groups,...) boxplot(data2~groups,...) boxplot(data3~groups,...) Is there a way to get these into a single pdf file? Thanks in advance... Mike Jones Westat 1650 Research Blvd. RE401 Rockville, MD 20850 Ph: 240.314.2312 [[alternative HTML version deleted]]

...i to go up to 26. Is there a way to do that? I can't seem to manually adjust i because from what I understand, R creates 100 long vector and uses that to "loops thru" and I'm not sure how to get at the index of that vector. Any suggestions? Thanks in advance. Mike Jones Westat 1650 Research Blvd. RE401 Rockville, MD 20850 Ph: 240.314.2312 [[alternative HTML version deleted]]

surely this not hard, but i can't figure it out. i'd like to overlay the results of two ecdf's. e.g. xx<--ecdf(x) and yy<--ecdf(y). i'd like to plot xx and yy on the same graph. thanks...mj [[alternative HTML version deleted]]

Hi, I'd like to return the rows of sampled values of a vector. Can't figure out how to do it. For example: I start with [3, 1, 7, 4, 10] that have position [1,2,3,4,5]. I sample [10,1,4] and I want to return [5,2,4]. I'm sure there's a simple way to do that but haven't been able to figure it out or locate it. Thanks in advance...mj [[alternative HTML version

hi all, i'm trying to get elements in a matrix into a vector. i need a "streamlined" way to do it as the way i'm doing it is not very serviceable. an example is a 3x3 matrix like 0 0 3 2 0 0 0 4 0 to a vector like 3 2 4 thanks...mj [[alternative HTML version deleted]]

Hi, Wasn't sure how to explain this problem succinctly in a title. I am trying to read in a text file that looks like: 0 1000 175 1 2 3 1 1000 58 0 2 9 2 1000 35 0 1 3 10 3 1000 300 0 2 4 5 10 11 18 4 1000 150 3 5 6 5 1000 100 3 4 6 7 18 6 1000 50 4 5 7 8 7 1000 155 5 6 8 19 8 1000 255 6 7 19 9 1000 200 1 10 12 10 1000 52

Is there a limit to this? I'm working with a .Rdata file about 190 Mgs in size and R won't open it...thanks...mj [[alternative HTML version deleted]]

Hello all, I'm having difficulty automatically saving graphs. Is there a way to save graphs from the graphics window using commands in the R console? Thanks very much. [[alternative HTML version deleted]]
