[Rd] Bug in plot.formula (PR#757)

[presnell@stat.ufl.edu]

Here's a simple example:

  > x <- rnorm(20)
  > y <- 1 + 10*x + rnorm(20)
  > plot(y ~ x, subset=2*(1:10),xlab="In",ylab="Out")
  Error in length(x) == l : comparison (1) is possible only for vector types

The problem seems to be in this section of the code for plot.formula:

  if (!missing(subset)) {
    s <- eval(m$subset, data, parent.frame())
    l <- nrow(data)
    dosub <- function(x) if (length(x) == l) 
      x[s]
    else x
    dots <- lapply(dots, dosub)
  }

Sorry, no time this morning to attempt a fix myself, but I thought it
best to get this in before 1.2 is released.
