Hi, I was trying to install Rgraphviz. I was able to download it with biocLite, but couldn't load the package. I have reproduced the error below: ------------------------------------------------------------------- > source("http://bioconductor.org/biocLite.R") > biocLite("Rgraphviz") Running biocinstall version 2.2.11 with R version 2.7.2 Your version of R requires version 2.2 of BioConductor. trying URL 'http://bioconductor.org/packages/2.2/bioc/bin/windows/cont rib/2.7/Rgraphviz_1.18.1.zip' Content type 'application/zip' length 1012303 bytes (988 Kb) opened URL downloaded 988 Kb package 'Rgraphviz' successfully unpacked and MD5 sums checked The downloaded packages are in C:\Documents and Settings\ts\Local Settings\Temp\RtmpQDoM9f\downloaded_packages updating HTML package descriptions > library("Rgraphviz") Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/Program Files/R/R-2.7.2/library/Rgraphviz/libs/Rgraphviz.dll': LoadLibrary failure: The specified module could not be found.

Hi I have encountered the same problem. One explanation might be that Rgraphviz and graphviz are out of sync: With graphviz version 2.2 (I think it was) I had the same problem, but if I installed graphviz version 2.16 things work fine Cheers S?ren ________________________________ Fra: bioconductor-bounces at stat.math.ethz.ch p? vegne af Tim Smith Sendt: ti 14-10-2008 19:15 Til: bioc Emne: [BioC] Rgraphviz install Hi, I was trying to install Rgraphviz.
