[R] Bug in termplot?

[Simon Wotherspoon]

Hi,
	Is this a bug in termplot, or (once again) do I just not understand what R
is really doing?


I am using termplot to contruct partial residual plots,
  1. For all terms at once
  2. One term at a time
but I get different results from these two methods.  To give a concrete
example, I would have thought the top and bottom rows of the plot
constructed with the following code would be identical.

Grateful for any clues

Simon.



## Term plot example

n <- 50
x1 <- 2*runif(n)
x2 <- 2*runif(n)
y <- x1+sin(x2)+0.1*rnorm(n)

fit <- lm(y ~ x1 +x2)
par(mfrow=c(2,2))
termplot(fit,partial=T)
termplot(fit,terms="x1",partial=T)
termplot(fit,terms="x2",partial=T)
