Version 0.4-0 of the `multcomp' package has just been uploaded to CRAN. Known bugs have been fixed and, inspired by some questions posted on r-help, methods for `lm' and `glm' objects for the generics `simint' and `simtest' have been implemented. Thanks to all bug-reporters! Torsten From the

[R] equivalent of Splus command axis(..., srt=45, adj=1) in R

Dear R-users moving from Splus to R (under Windows), I notice that command srt within a plot in the original Splus code is ignored by R. For example, if a plot something and then include the line of code axis(1, at=Time, labels=Text, srt=45, adj=1) the srt=45 command within the axis()

The usual assumption in regression is that noise is iid, that is has the same distribution except for a location shift at all values of x. Prediction intervals adopting this premise are based on an average of the noise over the whole sample and thus produce the result you see in your figure.
