Error when I attempt to create a list or a data frame
When I try to create a list with three classes of objects: a numeric, boolean, and vector of character data: lst <- list(c(1,2),TRUE,c(?a?,?b?,?c?)) I receive this error: Error: unexpected input in "lst <- list(c(1,2),TRUE,c(?" I receive a similar error when I create a data frame with mixed classes of objects. Thanks ahead of time!
