[R] help on establishing a matrix
I am a beginner and this is a naive question. I have the following data set. row column height 1 2 96 3 7 67 9 25 77 .. I have a matrix of 50*100 data points and about 60% of them are zeros. I want to put the height data into the matrix according to their row and column numbers. does anybody have experience in setting up such matrix? Your help is highly appreciated.

[R] FW: merge multiple csv files
Dear list:I have a folder that contains more than 50 csv files labels sequencially like sample01.csv to sample50.csv. for each file the first 5 rows are descriptive of the data collected (useful but not needed in data merge). each file then start the data at row 6 and have 2 variables x and y. In order to know which file one observation is from, I'd like to have a new variable location, for example if the data are from file sample11.csv, then the location for that obs is 11.Another difficulty is there might be two observations actually repetitive, for example sample05.csv might contain (4, 10) and (4, 12). I'd like to average it into (4, 11). Any suggestions are welcome.Jack Connect and share in new ways with Windows Live.
