I don't understand what my error is in the following:
I need to use the get command on a series of variables, but can't for
some reason that I don't understand.  Why am I told no such variable as
ov$vn1 after getting a summary report on that very variable?
> summary(ov$vn1)
     Min.  1st Qu.   Median     Mean  3rd Qu.     Max.     NA's
      1.0     25.0     81.0    468.1    450.0 159100.0   6050.0
> dvars <- paste("ov$dvn", 1:4, sep="")
> vars <- c("ov$vn1","ov$vn2","ov$vn3","ov$vn4")
> summary(get(vars[1]))
Error in get(x, envir, mode, inherits) : variable "ov$vn1" was not found
Execution halted
