Hello,
I would like to select cases using multiple logical operations (e.g. X
or Y or Z) without having to repeat the dataframe$variable within the
subscript. My working code (with a single logical operator) currently
looks like this:
dataframe$newvariable[data$oldvariable=="X"]<-"group1"
I thought this next line of code might do what I wanted, but it doesn't:
dataframe$newvariable[data$oldvariable=="X" | "Y" | "Z"]<-"group1"
I'd appreciate any suggestions. I've tried playing around with grep, but
can't make it work.
Thanks! Mark
