[R] filter data.frame with a vector

[Mat]

Hello together,

i have a data.frame, which i want to filter with numbers in a vector.
I have a vector (Top10) with these numbers:
 [1] 205 302 156 378 235 328 183 375 296 374
and i have a data.frame with a Column (CU_NO) with all my Customer numbers.

How can i filter this data.frame, with the Numbers in my vector.

this one doens't work:
data_export_final<-data_export[(data_export$KD_NR==Top10),]

Thank you.

Mat
