Dear list, I'm trying to arrange various grid objects on a page using a frameGrob. It works fine with basic grobs (textGrob, gTree, etc.), and also with ggplot2 objects using the ggplotGrob() function. I am however stuck with lattice. As far as I understand, lattice produces a list of class trellis, which is eventually displayed using the plot.trellis method. I am not sure if/how one can

Dear all I am working on unbalanced panel data and I can readily fit a "pooling" model using plm(), but not a "within" or "random" model. Reproducing the examples in vignette("plm") and in the AER package I encountered no such issues. ##unfortunately I cannot disclose the data, and it is too big anyway > dim(ibes.kld.exp.p[x.subs , ]) [1] 13189 34

Hi, I'm trying to get data from web page and modify it in R. I have a problem with encoding. I'm not able to get encoding right in htmlTreeParse command.

Hi folks, Wish y'all a Happy New Year 2010! I need some help with the following: Say I have lots of data sets, on which I have to apply a certain function on the same set of columns in each of the data set. Let's take, for ex, the typical data set is: df1 <- as.data.frame(cbind(rnorm(10),rnorm(10))) names(df1)[1] <- "A" names(df1)[2] <- "B" There are many

I?m trying to build a simple formula interface to work with a function using ggplot2. The following scheme ?works? up until the plot(p) request, at which point there are complaints about xlim?s and a blank graphics window. Looking at str(p) I do see the limits are NULL, plus layer 1 claims to have an empty data frame (but df is reproduced correctly). I'm sure I'm missing something really

Hello all, I am using quartz (on OS X obviously) to produce PDFs and PNGs from my plots, for later inclusion in LaTeX. I am typically using something like: plot(0) dev.print(quartz, file="foo.pdf", width=5, height=3) dev.print(quartz, file="foo.png", width=5, height=3, dpi=72) I want the sizes of the PDF and PNG to be *equal* in *inches*, which works with dpi=72. However,

Dear List, I would like to modify the settings for plotting a Vennerable object, but I don't know how...so if anyone has an idea I would be really graetfull. best, Fabian some R code to illustrate my problem: #### library(Vennerable) ven <- compute.Venn(Venn(SetNames=c("A", "B"), Weight=c(0,111,106, 26))) # now my problem is that whenever I plot the object, the

Dear all, I'm trying to write tabular data to a text file, these data will be the input of a Fortran program. The format needs to be "(i7,2x,7(e15.7,2x))". I have not been able to find a clean way of producing this output with write.table. I searched for a "write.fortran" function similar to read.fortran() in package utils but I couldn't find any. Below is a small

Hi I have a long data set on which I want to do Bland-Altman style plots for each rhythm type Using ggplot2, when I use geom_hline with facet_grid I get an extra set of empty panels. I can't get it to do it with the "Diamonds" data supplied with the package so here is a (much abbreviated) example: > lvexs cvd_basestudy ecd_rhythm fixed_time variable_time 1 CBP05J02

Dear all, This may be specific to Mac, I haven't had a chance to test another platform. Consider this, plot(1,1,t="n") rasterImage(matrix(1),1,1,1,1) library(grid) grid.rect(gp=gpar(fill="grey")) The grid.rect covers the full device window as expected. However, when I resize the window ever so slightly (interactive device) the rectGrob is suddenly clipped to the previous

[cc'ing to R-devel] It's moderately obscure to me too, but ... There are two sets of bessel code in the package, one in C++ from Chris Bond and the other in FORTRAN from Netlib (I think). The FORTRAN code is the one that's giving trouble, you might try just removing the FORTRAN code from the src directory and trying again.

When I invoke qplot, I get the following error: Error in rename.default(x, .base_to_ggplot) : object '.data' not found I would appreciate any advice. sessionInfo: R version 2.10.0 (2009-10-26) i386-pc-mingw32 locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C

Dear all, I am puzzled by the following behavior of the new grid.cap() function, which appears to run out of time when capturing the output of a graphic. It works fine if I introduce a Sys.sleep(1) before executing more code, library(grid) quartz() grid.circle(gp=gpar(fill="black")) gg <- grid.cap() dev.new() grid.raster(gg) ## completely blank gg[gg!="white"] ## indeed

Dear all, I got a couple of warnings using panel.levelplot.raster, In panel.levelplot.raster(..., interpolate = TRUE) : 'y' values are not equispaced; output will be wrong although I was quite sure my data were equally spaced (indeed, I created them with seq()). A closer look at the source code reveals that the function tests for exact uniformity in grid spacing, if

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
