Re: [R] Get bearing for cartesian coordinates

I think all you need is bearing - function(x, y) atan2(y, x)*180/pi This gives the bearing in degrees from the origin. If you wanted the bearing from some other point, just take the differences: bearing - function(x, y, origin = c(x=0,y=0)) atan2(y-origin[y], x-origin[x])*180/pi

Re: [R] local regression using loess

Bert Gunter gunter.berton at gene.com writes: Actually, loess is much more than an interpolant. I wouldn't even call it that. It is a local regression technique that comes with all the equipment you get in classical regression. But it is meant for normal-like errors, which is not

[R] some QCA questions

Dear Adrian Dusa, others, I've recently started to learn R in order to use the QCA package because i think it might offer what other QCA packages don't: possibilities for quite a few conditions and large n. However, can someone tell me approx. how much RAM i need to run QCA on set of +/-

Re: [R] aggregating strings

You are probably going to get tons of answers, as there are many ways -- and packages -- to do this (e.g. see packages reshape and plyr). However, you might want to take a look at ?tapply, for which aggregate() is a wrapper, for the basic core R approach. Bert Gunter Genentech Nonclinical

Re: [R] vary the parameters for a function

If you want to have a gui that allows you to change parameter values using buttons/sliders/etc. and see what the effects are, then look at the tkexamp function in the TeachingDemos package (see the examples on the help page). If you have a predetermined set of values for the parameter of

[R] Density plot in ggplot2

Hi all, I was trying to draw a stacked density plot like that : library(ggplot2); library(plyr) dat - cbind(rnorm(300), rep(c(1,2), each=150)) ggplot() + geom_density(aes(x=dat[,1], fill=factor(dat[,2]), position=stack)) + xlab() + ylab() + scale_colour_manual(name = Pallet,

[R] Skew-Normal Linear Mixed Model (SNLMM)

Dear ALL, In the Normal Linear Mixed Model (NLMM) we make the assumption that the random effects are normally distributed. Is it possible to fit a linear mixed model in R where the random effects are assumed to have a Skew-Normal distribution? I am trying to reproduce the results in the paper

Mika Are you familiar with item response theory? You might consider functions in ltm or MiscPsycho for dealing with binary response data. -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of mik07 Sent: Tuesday, July 28, 2009

Re: [R] Searching for specific values in a matrix

quick question, i am trying to get an interval of values now with this code by toggling the tolerance limit. is there any way i can modify this code to find values which are within limits of BOTH latitude and longitude? currently i have to pick one or the other. It's not really clear

Re: [R] Density plot in ggplot2

Hi Ron, I'm not sure why ylab doesn't work. Maybe a bug. I note the label doesn't get removed with labs() either. However using scale_y_continuous(name=) does remove the label. For the legend, you are using a fill scale, not a colour scale i.e. fill=factor(dat[,2]), not
