Try this:

matplot(DF[,c('SexRatio', 'lower', 'upper')], type ='b', pch = 19, col
= c(2, 1, 1))


Or you could have a look at plotCI() in the gplots package.
(There's also a plotCI() in the plotrix package.)

Hi,

I have a data frame like this:
var1=years
var2=Sex ratio (0<value<1)
var3=lower 95% confidence interval
var4=upper 95% confidence interval

Is there a way to add these confidence intervals to a plot like this?
plot(years,Sex ratio,type="b")

Thanks in advance for any response
