similar to: Reducing the size of pdf graphics files produced with R

Hi, Can we attach a more descriptive "label" (I may use the wrong terminology, which would explain why I found nothing on the FAQ) to variable names, and later have an easy way to switch to these labels in plots? I fear this is not possible and one must enter this by hand as ylab and xlab when making plots. Thanks in advance, Denis Chabot

Hi, I don't know if I am the first one to report the problem: in 2.8.0 dev2bitmap gained aa support, but "extra" is null if neither taa nor naa is specified. > dev2bitmap("plot.pdf",type="pdfwrite") Error in paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=", type, : object "extra" not found >

Hi list, When exporting to PDF a graph with a legend, in the final PDF, the text is going beyond the legend box. > dev2bitmap("test.pdf", type="pdfwrite", h=6, w=6) The legend looks OK on the screen. I noticed that the size of the legend box depends on the size of the screen window, which is not the case for other graphical parts (text of the legend, title, axis

Hi, I am fairly new to GAM and started using package mgcv. I like the fact that optimal smoothing is automatically used (i.e. df are not determined a priori but calculated by the gam procedure). But the mgcv manual warns that p-level for the smooth can be underestimated when df are estimated by the model. Most of the time my p-levels are so small that even doubling them would not result

Hi, I'm wondering why 48 %/% 2 gives 24 but 4.8 %/% 0.2 gives 23... I'm not trying to round up here, but to find out how many times something fits into something else, and the answer should have been the same for both examples, no? On a different topic, I like the behavior of NAs better in R than in SAS (at least they are not considered the smallest value for a variable), but at the

Hi, I don't understand the following. When I create a small artificial set of date information in class POSIXct, I can calculate the mean and the median: a = as.POSIXct(Sys.time()) a = a + 60*0:10; a [1] "2009-03-10 11:30:16 EDT" "2009-03-10 11:31:16 EDT" "2009-03-10 11:32:16 EDT" [4] "2009-03-10 11:33:16 EDT" "2009-03-10 11:34:16

Hi, As part of the legend to a plot, I need to have the "n" in italics because it is a requirement of the journal I aim to publish in: "This study, n = 3293" Presently I have: legend(20, 105, "This study, n = 3293", pch=1, col=rgb(0,0,0,0.5), pt.cex=0.3, cex=0.8, bty="n") I suppose I could leave a blank in place of the "n",

Hi, I'd been using R in the past and recently installed it on a new windoze 7 machine. There have been many issues with compatibility and 32/64 bit apps etc and I did find on google on isolated complaint that saveplot failed in scripts a long time ago. R seems to work fine except script-based plot saving as pdf has not worked. I have tried the following, none of which seem to function, xyz

Hi, I've looked at the parameters available for the legend function and cannot find a way to change the distance between the top of the box surrounding a legend and the legend's title. I have a math expression that raises the height of my title. If you don't mind the non-sensical title I give to the legend for this plot (Figure 3.20 in R Graphics): with(iris,

Hi, Sometimes data series (not necessarily time series) suffer breaks where data were expected, but not collected. Often the regular "lines" command to add such data to a plot is what I want, but other times I'd like the line to break where the data series is interrupted, instead of the line jumping to the next point in the series uninterrupted. Usually my data file

Hi, I have data on stomach contents. Possible prey species are in the hundreds, so a list of prey codes has been in used in many labs doing this kind of work. When comes time to do analyses on these data one often wants to regroup prey in broader categories, especially for rare prey. In SAS you can nest a large number of "if-else", or do this more cleanly with "select"

Dear list members, I have to combine dataframes together. However they contain different numbers of variables. It is possible that all the variables in the dataframe with fewer variables are contained in the dataframe with more variables, though it is not always the case. There are key variables identifying observations. These could be used in a merge statement, although this won't

Hi, I have used package quantreg to estimate a non-linear fit to the lowest part of my data points. It works great, by the way. But I'd like to extract the predicted values. The help for predict.qss1 indicates this: predict.qss1(object, newdata, ...) and states that newdata is a data frame describing the observations at which prediction is to be made. I used the same technique I used

Dear list, I've tried to search the archives but found nothing, although I may use the wrong wording in my searches. I've also double-checked the upData function in Hmisc, but it does something else. I'm wondering if one can update a dataframe by "forcing into" it a shorter dataframe containing the corrections, like the "update" provided in SAS data steps.

Hi, I'm trying to move to R the last few data handling routines I was performing in SAS. I'm working on stomach content data. In the simplified example I provide below, there are variables describing the origin of each prey item (nbpc is a ship number, each ship may have been used on different trips, each trip has stations, and individual fish (tagno) can be caught at each

Hello R users, I have to import a file with one column containing dates written in French short format, such as: 7-d?c-07 11-d?c-07 14-d?c-07 18-d?c-07 21-d?c-07 24-d?c-07 26-d?c-07 28-d?c-07 31-d?c-07 2-janv-08 4-janv-08 7-janv-08 9-janv-08 11-janv-08 14-janv-08 16-janv-08 18-janv-08 There are other columns for other (numeric) variables in the

Dear List, I am using the bioconductor package Category to do some gene enrichment analysis, and usually save my KEGGmnplot's using a dev2bitmap command. This has worked just fine, until suddenly earlier today I got this error-message: > dev2bitmap("04610_080721.jpg",type="jpeg", height = 10, width = 10, res = 200) Error in dev2bitmap("04610_CSF080721.jpg",

Hi there folks I have R 1.3.0 running on Red Hat Linux 7.1 with GhostView 3.5.8. When I produce a file like: > bitmap("foo.pdf", type="pdfwrite") > plot(foo) > dev.off() and then try to read it with gv, I get an unrecoverable error and nothing displayed. Any help as to whether this ***should*** work would be appreciated. cheers, John -- John Williams

Hi, I am trying to put some graphics I have generated from R on a webpage using dev2bitmap to create a bitmap, .BMP, file. When I look at my notes from 2 or 3 months ago I was successfully able to put the ACTIVE device plot result into a bitmap file using a command such as: dev2bitmap("InsectSpray.BMP") Job done! Now when I try the same command, I get the following: >

It would be nice for checking documentation to be able to generate the "see also" cross references (e.g. the list of functions where dev2bitmap is linked as a "see also" reference.) Perhaps this already exists? (BTW, it would be useful to have a "see also" reference to dev2bitmap in the help for postscript and for Devices.) Paul Gilbert
