Estimados usuarios de R: Soy nuevo en R, le ruego disculpa por mi *Ignorancia*. Estoy corriendo la siguiente instruccion, ggsave(paste('img/',plotName,'.png', sep='') y resulta el error: ggsave(paste('img/',plotName,'.png', sep='') Saving 7.32 x 4.87 in image Error in grDevices::png(..., width = width, height = height, res = dpi, :

Estimado Linis, Si estás bajo Windows y no has cambiado las rutas (también dentro de las funciones) es posible que no funcionen bien. Por ejemplo la sentencia paste('img/',plotName,'.png', sep='') deberías cambiarla por: paste('img\',plotName,'.png', sep='') o incluso por paste('img\\',plotName,'.png', sep='')

Estimados usuarios de R: Estoy corriendo el código de aqui: http://www.r-bloggers.com/visualizing-baltimore-2-vacant-property-and-some-more-crime/ y correr la siguiente instruccion: saveKde2Plot(burgDens, 'BurglaryKde2d', 'Burglary\n Density') Esta función incluye el comando ggsave( ... ), que genera el siguiente error: Saving 7.32 x 4.87 in imageError in

I am writing a rails app with my colleague who wrote a lot of the tests. He had to take a leave of absence due to a death in his family, and I am needing helps with changing the model so that the tests will pass in our spec file. Here is the model: class Worker < ActiveRecord::Base attr_accessible :first_name, :last_name has_many :writings end Here is the spec:

Buenos días, He cambiado la versión de R como siempre a través de: install.packages("installr") library(installr) updateR() En esta ocasión trabajando bajo windows 10. La versión 3.2.2 me ofrece menos mirror, pero mi principal problema es que no soy capaz de trabajar con Rcommander (ahora lo hago con RStudio) me da la siguiente salida: > utils:::menuInstallPkgs() --- Please select a

Hi, I really feel I've looked everywhere, although I know this can't be a hard problem. I'd like to be able to call the graph below as a function, but I can't get the function to recognize variables beyond 'dframe'. I've read through many papers on writing functions in R, but I can't get this to work. data <- data.frame('date' = as.Date(rep(c(15101,

Hello. I'm trying to make some graphics with nationalized labels (pdf for use in LaTeX document). On console (displayed on screen) using all looks ok: ----------------------------------------\/ data<-rnorm(100) hist(data,main='Rozk?ad g?sto?ci punkt?w', xlab='Warto?? na osi y', ylab='Cz?sto?? wyst?powania') -------------------------------------------/\ But

running pictex() plot(1:11,(-5:5)^2, type='b', main="Simple_Example_Plot") dev.off() (as in the pictex example, but with underscores instead of spaces). the TeX file contains \put {Simple_Example_Plot} [lB] <0.00pt,0.00pt> at 124.00 275.33 the underscores have a special meaning in TeX, so they should be quoted or converted to dashes. -- Sam Steingold

The conversion of RGB to CMYK takes place in PostScriptSetCol() starting at line 2900 of R-2.7.0/src/library/grDevices/src/devPS.c if(strcmp(mm, "cmyk") == 0) { double c = 1.0-r, m=1.0-g, y=1.0-b, k=c; k = fmin2(k, m); k = fmin2(k, y); if(k == 1.0) c = m = y = 0.0; else {c /= (1.-k); m /= (1.-k); y /= (1.-k);} r, g, and b have already been normalized to the

I'm build with the usage of the tcltk/tcltk2 package a gui which is started with rscript.exe. At this gui the user is able to open and close plot windows. Now I'm looking for a way that a r function is called when a grDevices::windows window is closed. Is there a way to attach a callback function or so, which would be triggert if the user click at close of the grDevices::window? My

The 'at a minimum' information requested by the posting guide is missing. According to their documentation the cairo default fallback resolution is now 300dpi, and when I run your example on Fedora 21 that is what the emitted postscript says it is. You can easily alter the R code to set it to something different: see http://cairographics.org/manual/cairo-cairo-surface-t.html for the

It appears that grDevices (and perhaps other R libraries) is built without passing C_VISIBILITY to PKG_CFLAGS (-fvisibility=hidden), while other libraries (e.g. utils) do use the flag. This results in potential crashes on linux in situations like using embedded R in another application that happens to export a symbol named similarly to one defined in R's library, since the runtime linker

Hi Z I think supporting HCL color spaces more, is a *very* good idea. However, I doubt many R users, understand the motivation for HCL color spaces. I've reproduced Ross Ihaka's notes on color, on my personal website: https://sites.google.com/site/spurdlea/exts/ihaka_r_stats_787_10_color.pdf (This has been reproduced with permission). Another good article is:

I happened to notice that this header file uses #import <Cocoa/Cocoa.h> This is the first time I came across the preprocessor directive #import; the first thing I found about it is this Q&A suggesting it's not portable nor standard C: https://stackoverflow.com/q/39280248/3576984 On the other hand, this exact invocation seems pretty common on GitHub
