Hi,
I seem to be having somewhat of an unusual data input problem with some of the data sets I'm working with and want to run a simulation on.
in the first data set I'm looking at, I have a text file where the spacing between columns varies. I've attached a snippet. Is there a way to read this into R? Basically, I want to ignore all the spaces to make new columns.
In a slightly different case, I have a long sequence of nucleotides (the letters are always either g,a,t,c). Is there a way to get each letter into it's own column so that I can then use it as a data set?
I'm kind of loathe to program a java/C program to do this if I don't have to and was wondering if a way in R exists for this.
Thanks!
Greg
