Goal : I want very small lines at the bottom on the x axis , if possible in the arrow forms instead of vertical lines on the whole graph.

[R] Randomizing one column in the dataMatrix
I have huge data file, and I would like randomize just one column at a time , is there any easy way?

[R] t.test : extracting Error
Hi Thanks for the reply. I implemented your solution to my problem but ... For some of my column there is not enough data to do t-test so it gives me error and stops the for loop, is any graceful way to check for error msg and say ok if there is no $p.value continue to the next column Once again thx for help. sata pinal wrote: I have two matrix with same dimensions. I want to do t.test using each column from 2 different matrix. Row n Column names in both matrix are same. e.g. Matrix1 id VC1 VC2 VC3 R 1 2 3 R1 4 5 6 R3 7 8 9 Matrix2 id VC1 VC2 VC3 R 10 11 12 R1 13 14 15 R3 16 17 18 want to do t.test using each column (with same name ) using Matrix1 and Matrix2 for eg t.test(Matrix1$VC1, Matrix2$VC1)$p.value What is the best way to do it. I have dataset with 4000 columns for each matrix with same row and column names. Thanks a lot. - Be a better sports nut! Let your teams follow you with Yahoo Mobile. Try it now.
