hello togehter, how can i match a complete data.frame to another one? I know i can match one column with that code: A<-match(data$PJ_ID,project$PROJ_ID) data$Name<-proj$Name[A]
How about: data <- data[ match(data$PJ_ID,project$PROJ_ID) , ] (Untested in the absence of data ... or 'data'.
but how can i match the total data.frame from project to data? indivduel matching for each column is not very productive....
