[R] Gantt chart problem after upgrade to R 2.4.0

[apjaworski at mmm.com]

This is interesting.  I am on Win2000 running R version 2.4.0 Patched
(2006-11-15 r39915) and plotrix 2.1.5.  I get the plot that scaled a little
differently that the 2.3.1 example but the dates look fine.  I ran the
original code posted by John cane with no changes (copy and paste).  I used
the windows device and did "Save As..." to save the PDF file.

Here is the code:

require(plotrix)
Ymd.format <- "%Y/%m/%d"
Ymd <- function(x){ as.POSIXct(strptime(x, format=Ymd.format))}
gantt.info <- list(
  labels=c("Dickens",   "Doyle",    "Kipling",  "Poe"),
  starts=Ymd(c("1824/01/01", "1850/01/01", "1865/01/01", "1815/11/01")),
  ends=Ymd(c("1901/01/01", "1922/01/01", "1935/01/01", "1867/01/01")),
  priorities =c(1,2,2,4))
gantt.chart(gantt.info,main="Writers",
  xlim=as.POSIXct(c("1810/01/01","1940/01/01")))

Here is the result:

Cheers,

Andy

I am on ubuntu linux with R 2.4.0 compiled and I get the same picture
as with yours with R 2.4.0.
