Ok, thanks,
I'll try with a simplier example:

I have a vector with 4 levels

dataframe 1
station temp

aaa        12
aaa        13
bbb        12
bbb        20
aaa        23
bbb        21
ccc        30
ccc        18
ddd        15
aaa        11
ddd        15
ddd        10


and a thresholds vector

station thr

aaa         20
bbb         18
ccc         25
ddd         10


I vant to select from dataframe 1 each value (level by level) > its own threshold value.
How to do it automatically? (vector temp and vector thr have different length)

Thanks
