Hi, I have a problem on my mac when trying in R to produce png images.
I am getting this warnings with the ArrayQualityMetrics package: > arrayQualityMetrics(rma_fatBody, outdir="normData", force =T) The report will be written into directory 'normData'. KernSmooth 2.23 loaded Copyright M. P. Wand 1997-2009 (loaded the KernSmooth namespace) libpng warning: Application built with libpng-1.2.26 but running with 1.5.2 [[1]] libpng warning: Application built with libpng-1.2.26 but running with 1.5.2 libpng warning: Application built with libpng-1.2.26 but running with 1.5.2 libpng warning: Application built with libpng-1.2.26 but running with 1.5.2 I am running the R 2.14 version using the R studio GUI. I am not excatly sure about the libpng problem. When I am doing locate libpng-config I'm getting several hits, some with libong-config12, some with libpng-config14, some without nay numbers: ayeroslaviz:~ ayeroslaviz$ locate libpng-config /Applications/XAMPP/xamppfiles/bin/libpng-config /Library/Frameworks/GTK+.framework/Versions/2.18.X11/Resources/bin/libpng-config /opt/local/bin/libpng-config /usr/X11/bin/libpng-config /usr/local/bin/libpng-config When doing which libpng-config I'm getting: /usr/local/bin/libpng-config Is there a way to uninstall older versions of libpng or update the paths to the right version. Unfortunately I am not even sure, what thesource of this warning, so I hope I gave here all the needed information. I would be grateful for anyone who gives me a hint about how to solve this problem. thanks A. > sessionInfo() R version 2.14.0 (2011-10-31) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) locale: [1] C/en_US.UTF-8/C/C/C/C attached base packages: [1] splines stats graphics grDevices utils datasets methods base other attached packages: [1] mirna20cdf_2.9.1 AnnotationDbi_1.14.1 arrayQualityMetrics_3.2.3 vsn_3.18.0 affyPLM_1.26.0 [6] preprocessCore_1.12.0 simpleaffy_2.26.1 gcrma_2.22.0 genefilter_1.32.0 siggenes_1.24.0 [11] multtest_2.8.0 affy_1.28.0 Biobase_2.10.0 BiocInstaller_1.2.1 loaded via a namespace (and not attached): [1] Biostrings_2.18.2 DBI_0.2-5 IRanges_1.10.4 KernSmooth_2.23-7 MASS_7.3-16 RColorBrewer_1.0-5 RSQLite_0.10.0 [8] SVGAnnotation_0.7-2 XML_3.4-3 affyio_1.18.0 annotate_1.28.0 beadarray_2.0.2 grid_2.14.0 hwriter_1.3 [15] lattice_0.20-0 latticeExtra_0.6-19 limma_3.6.9 marray_1.28.0 stats4_2.14.0 survival_2.36-10 tools_2.14.0 [22] xtable_1.6-0 > R.Version() $platform [1] "x86_64-apple-darwin9.8.0" $arch [1] "x86_64" $os [1] "darwin9.8.0" $system [1] "x86_64, darwin9.8.0" $status [1] "" $major [1] "2" $minor [1] "14.0" $year [1] "2011" $month [1] "10" $day [1] "31" $`svn rev` [1] "57496" $language [1] "R" $version.string [1] "R version 2.14.0 (2011-10-31)" > RStudio.version() [1] "0.94.84" [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
