Re: [R] barp {plotrix} Start bars at 0 with a vector of positive values
Hi Jim,
Yes, it seems to work. Thanks.
Regards,
Pascal

Hi Pascal,
Right again. This seems to work for both and I think handles the problem
correctly:
if(is.null(ylim)) {
negy<-any(height<0,na.rm=TRUE)
if(negy) miny<-min(height,na.rm=TRUE)*1.05
else miny<-ifelse(ylog,min(height)/10,0)
ylim<-c(miny,max(height,na.rm=TRUE)*1.05)
}
else {
miny<-ylim[1]
negy<-miny<0
}
Remove the line:
negy<-any(height<0,na.rm=TRUE)
and modify the succeeding conditional clause as above. This will appear
in version 3.5-8.
Jim

Re: [R] barp {plotrix} Start bars at 0 with a vector of positive values
Hi Jim, I tried your fix. This one works: barp(c(2,3,4,5,6,7,8), ylim=c(-10,10)) This one fails: barp(c(2,3,4,5,6,7,8)) Regards, Pascal On Fri, Jun 13, 2014 at 7:09 PM, Jim Lemon wrote: > On Fri, 13 Jun 2014 06:50:59 PM Pascal Oettli wrote: >> Dear list, >> >> Please consider the following example: >> >> library(plotrix) >> barp(c(2,3,4,5,6,7,8), ylim=c(-10,10)) >> >> How to force the bars to start at 0?

Re: [R] barp {plotrix} Start bars at 0 with a vector of positive values
Hi Jorge, It is in order to have different barplots with the same range of limits, to keep them easily comparable. Some have negative values, some others no.

Re: [R] barp {plotrix} Start bars at 0 with a vector of positive values
Hi Jim, Thank you for the suggestion. I will try it.

Re: [R] barp {plotrix} Start bars at 0 with a vector of positive values
Hi Pascal, Perhaps I am missing something, but what about changing passing ylim = c(0, 10) to barp()?

I think you can fix this by changing: negy<-any(height<0,na.rm=TRUE) to negy<-any(height<0,na.rm=TRUE) || ylim[1] < 0 I'll check this later (I'm just going out) and if it doesn't work, I'll send another email with something that does.
