Hi,

Does anyone know how i get rid of the marker point in my error bars? The
bars default function (it seems) is to have a dot in the middle of the bar,
however i don't want it there.

I am using Hmis to draw my errorbars and code is

a<-as.vector(tapply(Sporangia,list(Host,Isolate),mean))
b<-as.vector(tapply(Sporangia,list(Host,Isolate),sd))
c<-sqrt(b/36)

errbar(c(1.5,2.5,3.5,5.5,6.5,7.5),(tapply(Sporangia,list(Host,Isolate),mean)),a+c,a-c,add=T)

Cheers

Anna
