ComRades, On a recent Windows XP system that I have to use at work, I installed Tinn-R 2.3.4.4 and R 2.10.1 When I mark-select a piece of code, say summary(x) written in Tinn-R and send it to the RGui using the send button, the RGui console instead of showing me my piece of code, it shows something like source(.trPaths[5], echo=FALSE, max.deparse.length=150) The code is executed fine but if

Hello, I am trying to find out how can I generate the smallest R executable. R is to be run in a grid application, in batch mode, so I need a small exceutable, possibly getting rid of any interactive component. Should I look at the embedded version? Any other pointers?

Generally you'd use file() to open the file, then use readLines(), say inside a while() loop to read one `chunk' at a time. However, your example looks a bit strange. The possibility of empty line makes it a bit more complicated, by that last couple of lines seems to suggest that you could have a line of data follow by another line of data without variable label. If that's true, I

Dear list, I read in ?plotmath that I can use bgroup to draw scalable delimiters such as [ ] and ( ). The same technique fails with < > however, and I cannot find a workaround, grid.text(expression(bgroup("<",atop(x,y),">"))) Error in bgroup("<", atop(x, y), ">") : invalid group delimiter Regards, baptiste sessionInfo() R version

Podrías mandar un summary de tu conjunto de datos o un str para ver por que no puede estimar esos efectos, también sería útil el resultado de with(tusdatos, table(Landscape,Crop,Position)) Gabriela

Dear R user community I wanted to use "bgroup" for plotting a math formula with a big "{" on the left, and nothing on the right. i used text( 10, 10, pos=4, cex=1.8, expression(F(x) == bgroup("{", x, "")), ...) on a 40 x 20 plot. surprisingly, bgroup sets "Phi(xi) = { xi" i.e. replaces alphabetic characters with greek letters in the entire

I have a Sun 7310 storage server. This is running Solaris 10 but it's self-contained and I can't login to it or run Samba on it. I manage it with a web interface. I have a CentOS 5.3 machine that mounts a bunch of file systems via NFS from the Sun server. This works fine. I installed Samba 3.4.5 on the CentOS machine and configured it to share some of the directories that are actually NFS

Dear all, I'm using the curve() function to plot discharge Q against water depth a. However, I would like to have a graph of water depth a plotted against discharge Q. How can this be done? Minimal working example: S0 = 0.004 n = 0.04 tanalpha = 1.4/1.5 par(mar = c(5,5,1,1)) # b, l, t, r

Hola, ¿qué tal? Me han pedido que genere unos gráficos para insertarlos en un docuemento de Word. Yo suelo generar gráficas en formato PNG, pero me han dicho que "quedan mal". Y yo apenas sé nada de Word. ¿Cuál sería el formato gráfico más adecuado en este caso? Un saludo y muchas gracias, Carlos J. Gil Bellosta http://www.datanalytics.com

Hi folks, I've been using 'PBSmapping' to make a map of Europe with some labels. I've been using the 'worldLL' PolyData, as my computer is too slow to make my own from the GSHHS files. The only problem is this PolyData does not seem to include Ireland. I have no idea why this should be so, other European islands such as Sardinia etc. are included.

Buenos días a todos, Una pregunta muy sencilla, podrían por favor informarme dónde puedo conocer el significado de símbolos como $, %, == que se utilizan frecuentemente en R?

I know this a newbie question, but I've only just started using AIC for model comparison and after a bunch of different keyword searches I've failed to find a page laying out what the differences are between the AIC scores assigned by AIC() and mle.aic() using default settings. I started by using mle.aic() to find the best submodels, but then I wanted to also be able to make comparisons
