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
