Hi,
I am encountering a problem in reading a file,
the file looks like that:
T 3 0 -- -- -- T -- -- -- 18.98
3 1 6.75 4.39 39 -- -- -- 18.58
3 2 6.90 4.90 43 -- -- -- 18.63
3 3 7.07 5.39 48 -- -- -- 18.78
G 4 0 7.41 5.54 47 G -- -- -- 18.90
4 1 7.44 5.99 30 10.93 5.30 23 18.95
4 2 7.27 6.05 23 11.16 5.74 19 18.96
4 3 7.27 5.54 27 11.58 5.95 18 18.97
the first an the 7th column contains only T and G
my problem is i want to have the 4th column as a vector : 6.75, 6.90,
7.07, 7.41, 7.44, 7.27, 7.27.
when i do a simple read.delim(data, sep="", header=FALSE), i get this
T 3 0 -- -- -- T -- -- -- 18.98
3 1 6.75 4.39 39 -- -- -- 18.58
3 2 6.90 4.90 43 -- -- -- 18.63
3 3 7.07 5.39 48 -- -- -- 18.78
G 4 0 7.41 5.54 47 G -- -- -- 18.90
4 1 7.44 5.99 30 10.93 5.30 23 18.95
4 2 7.27 6.05 23 11.16 5.74 19 18.96
4 3 7.27 5.54 27 11.58 5.95 18 18.97
with the first line containing T, 3, 3, 3, G, 4, 4, 4 so the values are
shifted in the 1st and 5th row
i tried to change sep="" to sep="\t", but than i don't get a matrix
i just get a one column file.
" T 3 0 -- -- -- T -- -- -- 18.98"
" 3 1 6.75 4.39 39 -- -- -- 18.58"
" 3 2 6.90 4.90 43 -- -- -- 18.63"
" 3 3 7.07 5.39 48 -- -- -- 18.78"
" G 4 0 7.41 5.54 47 G -- -- -- 18.90"
" 4 1 7.44 5.99 30 10.93 5.30 23 18.95"
" 4 2 7.27 6.05 23 11.16 5.74 19 18.96"
" 4 3 7.27 5.54 27 11.58 5.95 18 18.97"
My question is there is a way to read the file either with skipping the
first column and the 7th,
Or how can i get to have a vector with the 4th column.
Thanks for the help,
Josephine
