Extracting specific columns from a data frame
I have an R data frame with 6 columns, and I want to create a new dataframe that only has three of the columns.
Assuming my data frame is df, and I want to extract columns A, B, and E, this is the only command I can figure out:
data.frame(df$A,df$B,df$E)
Is there a more compact way of doing this?
