hi there

I have a vector with a set of data.I just wanna seperate them based on the first p and q values metioned within the data.

[1] chr10p15.3 /// chr3q29 /// chr4q35 /// chr9q34.3
[2] chr1q22-q24
[3] chr1q22-q24
[4] chr1pter-q24
[5] chr1pter-q24
[6] chr1pter-q24

i used a regular expression [+q*] to match up the values but it matches q found anywhere i know i have written like that but i jus want it to match the first p or q values.

my result should be for q and
[2] chr1q22-q24
[3] chr1q22-q24

for p
[1] chr10p15.3 /// chr3q29 /// chr4q35 /// chr9q34.3

[4] chr1pter-q24
[5] chr1pter-q24
[6] chr1pter-q24
