Hi, I'm not being able to capture a position of a 'string' in a character string. In this example: 'There are 20 species in this grid' I would like to capture the string (number) after 'are' and before 'species'. Consider they do not change. I wouldn't like to use substr because stop position may change. Thanks Paulo

I got this error message. Error in .local(.Object, ...) : GDAL Error 2: CPLRealloc(): Out of memory allocating 16 bytes I was trying to read 1388 jpg images (993x993) with rgdal in a loop, to store data in a data.frame. It fails to read the 1338 image. Isn't R recycling the object? I'm running this process in a Server machine with Win XP x64, Xeon processor, 4GB Ram. R is

Hi, I'm trying to customize a window with 2 graphs. I'm able to do the first one with something like this general example par(mfrow=c(1,2),cex.axis=0.85,cex.lab=0.80,mai=c(1.3,1,0.5,0),las=3) bplot<-barplot(bar.values,names.arg=cf.names,width=0.5,ylab="% Area held") abline(h=0.3,lty=3,col="red") abline(h=0.1,lty=3,col="blue")

Hi, I'm trying to match two data frames in order to replace the boundary values in a dataframe.1 with values in dataframe.2 ONLY where the pair id1 id2 matches between the two data frames. Eg. > dataframe.1 ... id1 id2 boundary 3307 1095 1108 438.691 3308 1095 1109 438.691 3309 1095 1121 438.691 3310 1096 1109 438.691 ... 3345 1108 1120 438.691 3346 1108 1121 438.691 3347 1108

Is it possible to convert an hexbin object like hexbin(rep(1:100,each=100),rep(1:100,100),xbins=10) and convert it to a vectorial (shp) format?

I have a xml exported by Manifold GIS but I'm not being able to import it into R using XLM package. The file have this structure: <?xml version="1.0" encoding="UTF-8" ?> - <layout> <name>Layout 2</name> <pagesByX>1</pagesByX> <pagesByY>1</pagesByY> - <elements> <legend

Hi, well, I downloaded the head revision of llvm and llvm-gcc. As you said it hangs at: Formal argument #0 has unhandled type f32 /home/julio/trunk/llvm-gcc/gcc/libgcc2.c:1765: internal compiler error: Abortado Please submit a full bug report, with preprocessed source if appropriate. Actually, I don't need fp, there is any way to disable? By the way, I'm working with a MIPS coprocessor

And one last thing, the problem seems to be related to libcpp. Using only C frontend will work? 2008/7/7 Julio <julio.martin.hidalgo at gmail.com>: > Hi, well, I downloaded the head revision of llvm and llvm-gcc.

I agree non-vector. If nothing else a vector of complexes seems like a sensible concept which would be harder if a

Buenos días, alguien sabe si hay alguna manera de implementar una máquina de soporte vectorial (svm) con R-hadoop?? Mi interés es hacer procesamiento big data con svm. Se que en R, existen los paquetes {RtextTools} y {e1071} que permiten hacer svm. Pero no estoy segura de que el algoritmo sea paralelizable, es decir, que pueda correr en paralelo a través de la plataforma R-hadoop. Muchas

I'm trying to create a graph where different cells of a grid (a shapefile) will be painted with a color share scale, where the most easy way is to use gray(). Can I somehow get a vector (gradient) of colors, a vector of colors with other methods but gray()? I'm doing this until now quad_N_sp <-

Greetings All. Once again, I am probably missing something fairly accessible, but since I can't find it I'd welcome advice! I have a dataframe derived from a text file of data in tabular format. For one of the variables, say X, I want to select the subsets which in which X equals a particular value. Such values are given in the text file like: 2.3978953, and each such value will occurr

Hello everyone, this is a very simple question but I could not find the answer. :-( Is there any function in R for calculating the rank of a matrix? (In the sense of the dimension of the vectorial space that spans) Thank you in advance!

Hello, I am running R version 2.4.1 on Debian. I am using some R functions which produce several graphics displayed successively with an interactive prompt between each graph. For example, the plot.varest (vars) function produces such output (one graph per time series on which the VAR model is fitted). Plots on GARCH models also produce such outputs. Moreover, the frontend I am using for R

Hi everyone. I'm using this following code: pdf(file="Fig5.pdf", width = 4.86, height = 6.29, pointsize = 10, family ='Times') par(mfcol = c(3,2), mai = c(0.4,0.8,0,0), omi = c(0.7, 0, 0.7, 0.1)); hist( rnorm(100) ) dev.off() When I open this in any vectorial software (like Illustrator), it says that my font size is 7 instead of 10 that I specified. I have tried

Hola buenas tardes comunidad, seguro que hay algo fácil, pero se me escapa y es que estoy hoy algo torpe seguramente, a ver me gustaría hacer lo siguiente: Dada una matriz M (que puede ser muy grande), me gustaria crear un vector, sin usar bucles (ya que cuando es muy grande, todo puede ser muy lento) del siguiente modo. Para cada una de sus filas, me gustaría seleccionar un único elemento de una

Dear R-Listers, I'm a new R user and I've got some problems with copying/saving graphs in Windows Metafile Format. If I copy a graph from the R window (in Enhanced Metafile Format) and then paste it in WinWord 95, then everything is fine, apart from the fact that a) lines become a little bit thicker when the graph is printed; and b) dotted lines loose a little bit of resolution. However,

I have an XML file that has within it the coordinates of some polygons that I would like to extract and use in R. The polygons are nested rather deeply. For example, I found by trial and error that I can extract the coordinates of one of them using functions from the XML package: doc <- xmlInternalTreeParse('doc.kml') docroot <- xmlRoot(doc) pgon <-

Hello, I've been trying every now and then to find a cross operating system solution that would let me access PostgreSQL (and PostGIS) from R, or to access R from PostgreSQL. I know of pl/r, which accomplishes the latter, but has yet to be successfully ported to Windows. Similarly, I've tried to use Rdbi and DBI, but I haven't had luck with those on Windows either for connecting to
