Hello, I have some problems in using chron, Hmisc, and lattice. First,
using both chron and Hmisc, I get an error message when describing data:
df$Date <- chron(df$Date,format=c("d/m/y"))
> ll <- latex(describe(df),file="..//text//df.tex")
Error in formatDateTime(dd, atx, !timeUsed) :
could not find function "format.dates"
Then, using a chron object and lattice, I get
> plot.a <- xyplot(theta~Date|team,data=op.df.long,
+ strip = function(bg, ...) strip.default(bg = 'transparent', ...),
+ panel=function(x,y,...){
+ panel.xyplot(x,y,cex=0.4,col="black",...)
+ panel.loess(x,y,span=0.3,col="black",...)
+ panel.abline(h=0)
+ })
> print(plot.a)
Error in pretty(rng, ...) : unused argument(s) (format.posixt = NULL)
In both cases, the cron objects have been created using the function
chron(). Are lattice and Hmisc functions incompatible with chron, or am
I doing something else that causes these problems? Thanks, Ruud
