Dear Friends, I have a data matrix with 500 rows and 5 columns. The 1st row contains integer code (1, 2, 3). Other rows are real data. I want to convert the real data in 5th column based on CODES in 1st column, meaning conversion process are three types (depending on codes 1,2,3. Finally I want to use write.table command to get 500 rows with 6 columns (including converted data in 6th col).
how can i do it? i failed by matrix, read.table and write.table commands. i would appreciate, if someone helps me out.
