[R] glmulti fails because of rJava

Dear R, The glmulti package no longer loads through the library() command, apparently because of a problem with rJava. I have today reinstalled R from scratch (updated to v2.14.0) and reinstalled all packages from scratch and updated them all too. The problem is the same as I found on v2.13.2.

Re: [R] Linear regressions: producing multiple outputs

Hi RTSlider, I suspect you rather need to use the lme command (or perhaps glmmPQL or lmer) because you have a random predictor? lme(fixed=LeafLength~AirTemp*SnowFreeDate,random=~1|Species) See http://socserv.mcmaster.ca/jfox/Books/Companion-1E/appendix-mixed-models.pdf for a tutorial on lm

Re: [R] add error bars in a plot

Hi Maria, Instead of using errbar(), you can use the segments command which may be more flexible. Following the example on p.80 (the errbar command) of http://cran.ma.ic.ac.uk/web/packages/Hmisc/Hmisc.pdf set.seed(1) x=1:10 y=x+rnorm(10) delta=runif(10) barwidth=0.015 x11();plot(x,y) segments

[R] nls() fails on a simple exponential fit, when lm() gets it right?

he same exp and ln fits using MS Excel and the numbers returned are exactly as for the 'simpler ways', so nls is definitely in the wrong, but the self-start is almost identical to the one for the logarithmic fit, which works perfectly I can't see my mistake at all. Can anyone

Re: [R] round(1.5) = round(2.5) = 2?

a bit odd. However, R's benefits and advantages by far outweigh its little oddities, as I presume you know since you are using it. Effectively, I never use the round() command and always calculate using the floor function. Toby Marthews Le Dim 15 juin 2008 11:26, Markus Didion a écrit :
