similar to: cairo is not the default when available

Hello, Sorry if it is not the right place.. I installed R-2.13.0 on a x86_64 linux server. All went fine, but the svg() function yells: > svg() Error in svg() : cairo-based devices are not supported on this build I have the Cairo, cairoDevice, RSvgDevice packages installed, and running. > Cairo.capabilities() png jpeg tiff pdf svg ps x11 win TRUE TRUE TRUE TRUE TRUE

Hi, I am trying to build swfdec, but './configure' complains that it can't find 'cairo'. checking for CAIRO... no configure: error: cannot find cairo, which is required for build But I do have cairo: $ ls -la *ca* -rw-r--r-- 1 root root 317 Mar 1 2006 cairo-java.pc -rw-r--r-- 1 root root 271 Mar 15 2006 cairo.pc -rw-r--r-- 1 root root 333 Aug 4 2006 camel-1.2.pc

Is it expected that attributes set on a LGLSXP created by ScalarLogical will apply to all future objects created by ScalarLogical as well? For example: the 'test1' function below returns FALSE and 'test2' returns FALSE with an attribute: library(inline) test1 <- cfunction(body = 'return ScalarLogical(0);') test2 <- cfunction(body = ' SEXP success =

I believe the performance of isUnsorted() in sort.c could be improved by calling REAL() once (outside of the for loop), rather than calling it twice inside the loop. As an aside, it is implemented in the faster way in doSort() (sort.c line 401). The example below shows the performance improvement for a vectors of double of moving REAL() outside the for loop. # example as implemented in

Hi, configure fail on this message: > checking for PANGO... no configure: error: pangocairo is required to build swfdec I could not figure out what the missing package name on debian. There are a lot or package related to pango and cairo but none of those how seen to me relevant solve the problem. Please advise Addady

On Linux 2.13 by default links cairo, so png() uses it for rendering. One of my users has performance problem, so ask if it possible to temporary disable cairo during png() rendering so it reverts to grGraphics. My workaround for now is to configure R without cairo, but this affects all users that are forced to load and use CairoDevice if they wants better quality. I want to avoid this, is it

I'm playing with software RAID and LVM in some virtual machines and I've run into an issue that I can't find a good answer to in the docs. I have the following RAID setup: md0: sda1 and sdb1, RAID 1. This is /boot md1: sda2 and sdb2, RAID 1. This is a PV for LVM. VolGroup00, this is the volume group and md1 is the only PV in it. LogVol00 is swap LogVol01 is / LogVol02 is /home

I am installed CENTOS 5.5 on X86. After finish, I tried to apply latest patches. Rpm patch manager say need "dependency" "tzdata-java-20101-1.e15". I search CENTOS 5.5 CD and can NOT find this file. I also search Internet and no result. Can anyone tell me where to download "tzdata-java-20101-1.e15" RPM? Thanks.

R internally uses R_isForkedChild to prevent certain operations within the fork. However I don't think this is exported anywhere. You could do something like: extern

It is quite known that R documentation on R C api could be improved... Still R-package-devel mailing list should be preferred for this kind of questions. Not sure if that is the best way, but works. call_to_sum <- inline::cfunction( language = "C", sig = c(x = "SEXP"), body = " SEXP e = PROTECT(lang2(install(\"sum\"), x)); SEXP r_true =

Thanks Jan and Tomas for the feedback. Answer from Jan is what I am looking for. Maybe I am not looking in the right place buy it is not easy to understand how these LCONS, CONS, SETCDR...etc works.
