Hello list, I'd like to use a variable (or a column of a data frame) by using its name as a string. E.g.: Data2003 <- c(150,200,120) Data2004 <- c(145,211,110) myvar1 <- "Data2003" myvar2 <- "Data2004" # now I'd like do do this total <- Data2003 + Data2004 # in any way like # total <- ???(myvar1, myvar2) # or # total <- ???(myvar1) + ???(myvar2) # or something like that Is there a possibility to do this in R - can't find a solution! Thanks a lot
