Hi, on Windows XP Pro with R version 2.7.1 Patched (2008-06-27 r46012) the 'Cairo' and the 'EBImage' packages does not play well together.
Loading EBImage before Cairo cause the following to happen: # Rterm --vanilla > library(EBImage); > library(Cairo) Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/PROGRA~1/R/R-2.7.1pat/library/Cairo/libs/Cai ro.dll': LoadLibrary failure: The specified procedure could not be found. Error : .onLoad failed in 'loadNamespace' for 'Cairo' Error: package/namespace load failed for 'Cairo' with a dialog titled 'Rterm.exe - Entry Point Not Found' saying 'The procedure entry point cairo_pdf_surface_create could not be located in the dynamic link library libcairo-2.dll'. Loading the packages in the reverse order works, but the Rterm seems unstable, e.g. calling q() immediately after will exit the R session without questions: # Rterm --vanilla > library(Cairo) > library(EBImage) > q() [Immediately back to the command line]. I cannot reproduce the problem on R v2.7.1 on Ubuntu Hardy. > sessionInfo() R version 2.7.1 Patched (2008-06-27 r46012) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MON ETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] EBImage_2.4.0 Cairo_1.4-2 Cheers Henrik ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
