[R] plotCI

[Bernardo Rangel tura]

Hi R masters!


I need a Help with plot confidence intervals  for one equation. I use 
library gplots and plotCI command in this script:

require(gplots)

ano <-1980:2002

rf<-exp(91.37162-0.04720281*ano)

ciw.f<-sqrt(1.766073e-08)

plotCI(ano,rf,uiw=ciw.f)



But in the graph not shown the errors bar and  I have this error msg

zero-length arrow is of indeterminate angle and so skipped


Well, where is my eror?


Thanks in advance
