Odp: Tables
Hi r-help-bounces at r-project.org napsal dne 26.03.2009 16:39:18:
Hi, I am just starting using R. Hence, sorry for asking probably rather easy
questions. I used "read.table" to bring an .txt Table to R. Unfortunately the columns do not have the same length. I tried "fill=TRUE", to fill the blank space with "na". In a certain kind of way it worked, but befor filling the spaces it moved data from later columns to the first: 1 a b c 1 a b c 2 a b c 2 a b c 3 a b c 3 a b c 4 b c 4 b c NA 5 c 5 c NA NA
How do you know that c is in third column? If you can expect fixed width fields try read.fwf but if there is nothing what separates fields and they have variable length it would be quite difficult. Maybe to read each line and then to use some regexpr function no properly divide each line into appropriate columns. But maybe somebody will come with better idea. Regards Petr
What is my mistake? Thank you Sebastian --
