Hello,
consider the following data.frame df and vector v
df <- data.frame(group = c("A","B","C","D"), value = c(1,2,3,4))
v <- c(2,3)
How can I return a sub data.frame which has only the rows left where value
matches v
df:
group value
B 2
C 3
Cheers

df[df$value %in% v,]
group value 2 B 2 3 C 3 df is a function; you're better off not using that name for your dataframe. Sarah
