Hi, I'm studying the Michael J. Crawley book (Statistics An Introduction using R)and I'm trying to reproduce one example (page 168) for plot a barplot with error bars, but when I put the function I receive the following message. Please, could someone told me what's wrong? error.bars=function(yv,z,nn){xv=barplot(yv,ylim=c(0,(max(yv)+max(z))),names=nn,ylab=deparse(substitute(yv)))g=(max(xv)-min(xv))/50 for(i in 1:length(xv)){lines(c(xv[i],xv[i]),c(yv[i]+z[i],yv[i]-z[i]))lines(c(xv[i]-g,xv[i]+g),c(yv[i]+z[i],yv[i]+z[i]))lines(c(xv[i]-g,xv[i]+g),c(yv[i]-z[i],yv[i]-z[i]))}} Erro: unexpected symbol in "error.bars=function(yv,z,nn){xv=barplot(yv,ylim=c(0,(max(yv)+max(z))),names=nn,ylab=deparse(substitute(yv)))g" Sueli Rodrigues Eng.
