I'm working on linux server: Linux 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux
I get error while creating png files. I'm sharing my commands and error while I run those commands: >png("abc", type="cairo") Error in .External2(C_X11, paste0("png::", filename), g$width, g$height, : unable to start device PNG In addition: Warning message: In png("abc", type = "cairo") : unable to open connection to X11 display '' > png("apoeqqplot.png", res=600) Error in .External2(C_X11, paste0("png::", filename), g$width, g$height, : unable to start device PNG In addition: Warning message: In png("apoeqqplot.png", res = 600) : unable to open connection to X11 display '' dev.off() R version 3.4.2 (2017-09-28) Platform: x86_64-pc-linux-gnu (64-bit) Running under: Debian GNU/Linux 9 (stretch) Matrix products: default BLAS: /mnt/mfs/cluster/bin/R-3.4/lib/libRblas.so LAPACK: /mnt/mfs/cluster/bin/R-3.4/lib/libRlapack.so locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=en_US.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] CMplot_3.3.1 loaded via a namespace (and not attached): [1] compiler_3.4.2 tools_3.4.2 How do I fix this?
