Dear all, I would like to erase the content of a dataframe -- but not the dataframe itself -- in a simple and fast way. At the moment I do that by re-defining the dataframe itself in this way:
> df <- data.frame(A = numeric(), + B = numeric(), + C = character()) > # assign > A <- 5 > B <- 0.6 > C <- 103 > # load > R <- cbind(A, B, C) > df <- rbind(df, R) > df A B C 1 5 0.6 103 > # erase > df <- data.frame(A = numeric(), + B = numeric(), + C = character()) > df [1] A B C <0 rows> (or 0-length row.names) > Is there a way to erase the content of the dataframe in a simplier (acting on all the dataframe at once instead of naming each column individually) and nicer (with a specific erasure command instead of re-defyining the object itself) way? Thank you. -- Best regards, Luigi ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
