Hi
I tried to plot something simple
x=c('2010-08-20', '2010-08-30')
y = c(1,2)
t = strptime(x, "%Y-%m-%d")
plot(t,y)
At the xlab, the fonts are Chinese. How can I switch it to English? I am
working under Windows 7 64 bits Home Edition and R is Win32 version 2.11.1
Is this covered by the Windows FAQ at
http://cran.r-project.org/bin/windows/base/rw-FAQ.html
especially Qs 3.2 and 3.3? (We don't know what you see in Chinese.)
I suspect the issue is the locale category LC_TIME which is used to
'print' date-times (and in my UK locale I get an x axis annotated ny
'Aug'). If I do
Sys.setlocale('LC_TIME', 'zh_CN.utf8')
[1] "zh_CN.utf8"
plot(t,y)
I get Chinese labels ....
If so, you can also use a different format for the annotations: see
?axis.POSIXct, e.g.
plot(t, y, format='%m/%d')
Thanks!
