Hi, I'am trying to generate a PS Graphic under Windows with a fixed location via postscript(file="C:\\test.ps") But I always become the error: unable to start device PostScript can not open 'postscript' file argument 'c:\test.ps' There must be a very simple thing, that I make wrong. Thanks in advance Sigbert Klinke

Hi, I think you are right, legend cannot do it. I have now created my own legend function where I changed only one line and now it works the way I want it to. But I'm not sure if that might not have other side effects. I have the impression that the legend and the title start at the same y-position (try y.intersp=0). Only if y.intersp is big enough, then it leads to a non-overlap of

Hi, I want to compute the quantiles of Chi^2 distributions with different degrees of freedom like x<-cbind(0.005, 0.010, 0.025, 0.05, 0.1, 0.5, 0.9, 0.95, 0.975, 0.99, 0.995) df<-rbind(1:100) m<-qchisq(x,df) and hoped to get back a length(df) times length(x) matrix with the quantiles. Since this does not work, I use x<-c(0.005, 0.010, 0.025, 0.05, 0.1, 0.5, 0.9, 0.95, 0.975,

Hi, is there any other routine for factor analysis in R then factanal? Basically I'am interested in another extraction method then the maximum likelihood method and looking for unweighted least squares. Thanks in advance Sigbert Klinke

Hi, I am using reticulate and a virtual environment (not conda) to run Python scripts from RStudio. However, when I try to use my own (existing) virtual environment, reticulate does not use it. If I run my scripts, the installed modules (e.g., py_install("pandas", "mmstat4.hu.data")) are not found. I believe this happens because reticulate is using r-reticulate instead of

Set the legend position explicitly with x and y values and add xpd = TRUE to the legend call to clip the plot to the figure region and not the plot region (the default). Something like this (you may have to fool around with y.intersp, etc. to allow enough space between the legend lines): plot(c(0,1), c(0,1), type="n") legend(x = .4, y = 1.25, legend=c("", "",

Hi, I would have expected that I get always 3 colors as result which is not true: hcl.colors(3, alpha=c(0, 0.5, 1)) # 3 colors rainbow(3, alpha=c(0, 0.5, 1)) # 3 colors heat.colors(3, alpha=c(0, 0.5, 1)) # 3 colors terrain.colors(3, alpha=c(0, 0.5, 1)) # 6 colors cm.colors(3, alpha=c(0, 0.5, 1)) # 6 colors topo.colors(3, alpha=c(0, 0.5, 1)) # 9 colors R-Version and

Have you tried https://rstudio.github.io/reticulate/ ? Generally speaking, complex nonstandard package specific questions such as yours rarely get a reply here -- there are 20,000+ packages (and counting) after all! As reticulate was created by and integrated with RStudio/Posit, I would think their site and help resources might be a better venue. Of course, if you don't use RStudio, you may

If you don't know the name of the attributes in advance, how can you know the function name to be able to call it? This seems like a very flawed approach. Also, I would discourage the use of eval(parse(text = )), it's almost always not the right way to do what you want to do. In your case, eval(bquote(function(x) attr(x, .(n)))) would be better.

Hi, I would like know if there are any plans for some "standardized" syntax highlighting of R code? * Currently I'm using minted for my LaTeX slides with pygmentize and I do not know what scheme is used for highlighting the R code. * RStudio uses (as default) TextMate (Text editor for MacOS) highlighting for R code. * The R package "highr" just defines CSS classes and

Hi, from the documentation of help.search I think that fields like "concept" and "keywords" in the R help database exists. How can I access them from R? If I do > help<-help.search("blabla") > colnames(help$matches) [1] "topic" "title" "Package" "LibPath" then I get back only back these 4 fields. Thanks Sigbert

Hi, my MWE is not working as expected: plot(c(0,1), c(0,1), type="n") legend("top", legend=c("", "", "a"), col=c("blue", "red", "green"), title="test", y.intersp=0.2, lwd=1) The lines are not below the title. I want (nearby) lines as in the plot, but below the title. Is there a way to achieve this?
