I recently tried to run some sample code from  R package: circlize,
and got an error message (please see below) ===== > library(circlize) > circos.genomicInitialize(df) > df = data.frame(name = c("TP53", "TP63", "TP73"), + start = c(7565097, 189349205, 3569084),
+ end = c(7590856, 189615068, 3652765),
+ stringsAsFactors = FALSE) > df name     start       end
