[R] data which has different size of elements in each row
Hi all,
I have problem reading in a text file as follow.
The following data has not column header. I tried the following
command but failed,
temp<-read.table("data.txt",header=F)
An error message stated that line 3 did not have 4 elements.
0.293290E-05 0.117772E-05 -0.645205 rs2282755
0.307521E-05 0.000314 0.412997 rs1336838

0.977861E-05 0.070474 0.294653 rs2660664
0.122767E-04 0.156325E-04 0.569826 rs6870519
0.227205E-04 0.000189 -0.472862 rs10488345
Does anyone know how to solve it?
Thanks in advance for your help.
