I have a statement like below.

my_num <- 

"my_df" has 8,000 different STREPS in it.

I have a statement where I can select ONE item from data frame "my_df"
txhd_df <- prec_dist_df[ my_df$STREP=="101", c("COUNTY", "FIPS", 

I would like to make R compare and deliver only the STREPS that are in 

A comparative SQL command WHERE STREP 

Thanks for any help,
