linux - display.im6: no decode delegate for this image format `/tmp/magick-KFcbfWUi' -
i'm using rio , have sample.csv looks following hour,count 0300,0 0300,0 0300,1 0300,1 0300,2 0301,1 0301,2 0301,2 0301,3 i run following command: $ < sample.csv rio -ge 'g + geom_bar(df, aes(hour, count))' | display and display.im6: no decode delegate image format `/tmp/magick-gvr3krzh' @ error/constitute.c/readimage/544. from know geom_bar expects dataset first df , columns, i'm not sure why don't see graph, knows missing? thanks see docs.ggplot2.org/0.9.3.1/geom_bar.html . expects mapping first, data. , don't have specify df data, because it's been captured in g . and think need specify stat='identity' if want specify y aesthetic.
