Hi Peter, You didn't give a very specific example, but it seems to me that what you wish to do is not really complicated. I suppose you have created a table of sequences vs. say hyprophobicity, charge, etc..., something like... seq hydroph arom b0001 0.104762 0.000000 b0002 0.035122 0.065854 b0003 0.024193 0.070968 b0004 -0.096729 0.084112 b0005 -0.973469 0.091837 b0006

Gents: (alas, I think no ladies need to be included in the salutation) The apply() Help file says "... If the calls to FUN return vectors of different lengths, apply returns a list of length dim(X)[MARGIN]. " Shouldn't that be: "If the calls to FUN return vectors of different lengths, apply returns a list of length prod(dim(X)[MARGIN]). " Also, might you wish to add:

Dear All, I tried to draw 3 filled.contour plots on one page, but failed. It returns "Error in plot.new() : Figure margins too large". Can anyone help me to do this.

Hi all, I have a data frame with sequences of x and y from a map. I would like to know it both ways: 1. How to make a matrix from that; 2. how to make a data frame of all points in a map. Probably it is a silly question, but please tell me where to read about it or tell me how to do it. Miha Staut

Dear all, I am grateful if anyone provides a solution to my problem of no y-axis label using png on linux. If I use postscript device or X11 device, it is fine. On Windows, it works with png.

Hi all, I tried to produce some kriged surfaces with geoR (latest version). The size of the grid should be around 900 x 650 cells (what I find is not a very big grid), and the number of points is around 2500. The command krige.conv stopped after arround 5 min saying it can not allocate a vector with around 1.5 billion units. Sounds reasonable. Is there a workaround? How would I partition the

Dear all, I have a question about merge two character vectors of the same length into one. For example: X= c('A', 'B', 'C', 'A', 'D', .......) # 26 possible alphabet values with length 1000 Y=c('B', 'A', 'C', 'A', 'C', ........) # 26 possible aphabet values with length 1000

Hello, Gurus, recently I got a MIPS computer installed with Linux OS(Fedora), unfortunately there is no driver for the graphics card, so it cannot perform 3D acceleration. Since I happen to have a nVidia graphics card at hand (it is GeForce 9500GT, somewhat old), I want to apply this card on this computer, so my questions are: 1. Is it possible to make a nVidia graphics driver for this MIPS
