[R] Basic question ( too broad for help topics).

[Jim Burke]

I have searched help topics but don't know exactly what to search for.
Need to use my_num to find any matching STREPs in my_df

my_num <- 
c("101","102","103","104","105","107","108","112","113","114","115")

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

##  I have a statement where I can select ONE item from data frame "my_df"
out_df <- my_df[ my_df$STREP=="101", c("COUNTY", "FIPS", "STSEN", 
"STREP", "PREC")]

## A comparative SQL command
## SELECT
## COUNTY, FIPS, STSEN, STREP, PREC
## FROM my_df
## WHERE my_df.STREP 
IN("101","102","103","104","105","107","108","112","113","114","115")
## ORDER BY STREP;

Thanks for any help,
Jim
