Dear R helpers

Suppose

val1 = c(10, 20, 35, 80, 12)
val2 = c(3, 8, 11, 7)

I want to select either val1 or val2 depending on value of third quantity val3.

val3 assumes either of the values "Monthly" or "Yearly".

If val3 = "Monthly", then val = val1 and if val3 = "Yearly", then val = val2.

I tried the ifelse statement as


ifelse(val3 = "Monthly", val = val1, val2)
 
I get following error

> ifelse(val3 = "Monthly", val = val1, val2)
Error in ifelse(val3 = "Monthly", val = val1, val2) : 
  unused argument(s) (val3 = "Monthly", val = val1)

> val
Error: object 'val' not found

Kindly guide.

Regards

Vincy
