Hi, I have some old programs running well for older versions 2.2.0 and
2.1.1, but cannot run under 2.3.0. The problem is in plot with dates as x:
library(survival)
test <- data.frame( x = c(1:20), date = as.date(1:20))
plot(test$date, test$x)
---------------------------------------------------------
Error in plot.window(xlim, ylim, log, asp, ...) :
"log=" specification must be character
Is this a bug in v2.3.0?
Thanks,
Jun Zang
