I have three variables in a data frame and would like to swap the 4 columns around from
"dam" "piglet" "fdate" "ssire" to
"piglet" "ssire" "dam" "tdate" Is there any way I can do the swapping using R?
Any help would be very much appreciated.

Thus, to convert columns of an R data frame into rows we can use transpose function t. For example, if we have a data frame df with five columns and five rows then we can convert the columns of the df into rows by using as. data. frame(t(df)).
To interchange rows with columns, you can use the t() function. For example, if you have the matrix (or dataframe) mat you can transpose it by typing t(mat) . This will, as previously hinted, result in a new matrix that is obtained by exchanging the rows and columns.
dfrm <- dfrm[c("piglet", "ssire", "dam", "tdate")] OR:
dfrm <- dfrm[ , c("piglet", "ssire", "dam", "tdate")] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
