Re: [R] lattice strip.custom function

1. Please do not post in HTML. This is a plain text list and it can get mangled. 2. Thank you for the example data and code. The problem is -- see the Help for strip.custom() -- that strip.custom() wants a character vector or expression for the factor.levels argument. But... > str(dist.names) F

[R] lattice strip.custom function

I would like to use a mapping to name panel strips. Directly using mapping table does not work. What is the problem here? my.df <- data.frame(x = rnorm(100, mean = 0, sd = 2), name = "A") my.df <- rbind(my.df, data.frame(x = rnorm(100, mean = 0, sd = 4), name = "B")) my.df <- rbind(my.df, data.f

Re: [R] : Ramanujan and the accuracy of floating point computations - using Rmpfr in R

You can do that with bc if you pass the entire expression to bc(...) in quotes but in that case you will have to use bc notation, not R notation so, for example, exp is e and atan is a. > library(bc) > bc("e(sqrt(163)*4*a(1))") [1] "262537412640768743.2500725971981856888793538563373369

Re: [R] what constitutes a 'complete sentence'?

I encountered this a few months ago and, in my case, the sentence had a noun and verb but lacked a period at the end of the sentence. I tested that 'blah blah blah.' would have passed in that version of R-devel. Whenever I find a new rule or test with R CMD check, I tell myself that it must be

Re: [R] matrix -> delete last row -> list

Well 'list' in R is pretty naturally the same as R's 'atomic vector' in scads of languages. In R the term needs special care since it's still a 'vector'. 'Degenerate dimension' is probably a helpful phrase for understanding what is happening here. Cheers, Mike On Saturday, July 4, 2015, Rolf Tur

Re: [R] timePlot legend

Hi ulasim77, At a guess, what you want is to move the legend from beneath the plot to the right side. As none of the examples from the "plotTime" function seem to work, I'll have to use something simpler: par(mar=c(5,4,4,8)) plot(1:5) legend(5.4,3.2,c("First","Second","Third"),lty=1:3,col=1:3,pch=
