R switch() how to compare cases to a vector?

Question

I\'ve got a little issue with the switch statement in R. The following code is OK ... :

    value = \"B\"
  switch(value, 
         \"A\"={
           print(\"         


        

Answer 1

Try using vapply.

i.e. in your case

vapply(mychr,switch,"",...SWITCH ARGS...)

I think what you would want is:

vapply(mychr,switch,"",
               mychr[1]=mychr[1],mychr[2]=mychr[2],mychr[3]=mychr[3],"Other !!!")
