Dear R community In a current paper, I'm (briefly) considering the topic of producing scatterplots or maps with point labels positioned in such a way as to minimize label overlap and occlusion. This is a topic with a large, but scattered literature. In CS, it is considered NP-hard, but there are a variety of approximate solutions. The most complete bibliography I've found is the

Dear list, I'm having trouble to see how my elements on a 4 dimensional array are listed. For example, I generated the following array: junk.melt=melt(occ.data,id.var=c("Especie", "Site", "Rep", "Año"), measure.var="Pres") y=cast(junk.melt, Site ~ Rep ~ Especie ~ Año) Now, I want to be able to look at how my species (Especie) are listed, in

Hello, I have two vectors, one with 13112 points and the other one with 10909. I wonder if there is a way to interpolate the data so the shorter vectors has the same number of points as the longer one. Best, Dani -- Daniel Valverde Saub?

Hello, I have the next function call: lme(fixed=Error ~ Temperature * Tumour ,random = ~1|ID, data=error_DB) which returns an lme object. I am interested on carrying out some kind of lsmeans on the data returned, but I cannot find any function to do this in R. I'have seen the effect() function, but it does not work with lme objects. Any idea? Best, Dani -- Daniel Valverde Saub? Grup

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello: I'm having problems with this line of code: X.lm <- lapply(names(d), function(x) lm(d["cls"] ~ d[x], data=d)) d[x] is what is giving trouble here, but I don't know exactly how to solve it. What I'm trying to do is to create a linear model from each column of the data frame 'd' to apply ANOVA later. Thanks
