selection of character
Hi all,
I have a simple question:
I have a character vector like this
[1] "10_1" "1_1" "11_1" "2_1" "3_1" "4_1" "5_1" "6_1" "7_1" "8_1"
[11] "9_1" "1_3" "2_3" "3_3" "4_3" "1_4" "2_4" "3_4" "4_4" "5_4"

#2_2 4 1.0? 0 4
A.K.
I have two vectors one numeric and another with operand.
Eg: x - 1,2,3,4 and y-"*", "/", "-", "+"
I need to calculate all the possible two combinations in x with
each of operand in y. As example, 1*2,...

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
