Hello, I have a problem with the "do.call-function". I would like to merge the values of more than 30 columns, but not in all of the rows exist values, so with this commando i get a lot of ";" or NA.
How get i only the merge of cells with a number? datos$NEW <- do.call(paste, c(datos[,19:53], sep = ";")) $ NEW : chr "218.0;;;;;;;;;;;;;;;;;;;;;;;;NA;;;NA;;;NA;NA;NA;NA;NA I hope you can help me. Thanks!
