Crazy plots of time-series against dates
OK, it works. xlab and ylab had to be set properly. If you want to see what actually goes on, try: a<-chron(1:2000) b<-1:2000 plot(a,b,type="l") Marco Taboga (mtaboga at tiscalinet.it) ----- Original Message ----- From: "Peter Dalgaard BSA" <p.dalgaard at biostat.ku.dk> To: "Marco Taboga" <mtaboga at tiscalinet.it> Cc: "Thomas Lumley" <tlumley at u.washington.edu>; <r-help at stat.math.ethz.ch> Sent: Tuesday, May 01, 2001 7:43 PM Subject: Re: [R] Crazy plots of time-series against dates

display
the plot without first loading the chron library, the plot is OK, but
the
dates on the time axis are replaced by sequential numbers. I send you an attachment with the zipped plot, so you can see it. Thank you. Marco Taboga (mtaboga at tiscalinet.it)
Interesting effect... I don't know what the real cause is, but evidently it is the axis labels that are off (looking like what you get from applying deparse to a vector/chron object), so a quick fix would be to set xlab and ylab to sensible text strings. I.e. plot(a, b, type='l', xlab="a", ylab="b) Do you think you could cook up a small example (e.g. using simulated data) exhibiting the same behaviour? -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
