Is there an easy way to make the error bars the same color as the points and
lines they are plotted with.
My example
# fake data
x=sample(1:10, 100, replace =T)
y = rnorm(100) + runif(100)
df=data.frame(x,y)
# summarize data
m = aggregate(df,list(x),mean)
se = aggregate(df,list(x),sd)/sqrt(10)
library(Hmisc)
plot(x,y)
errbar(m$x, m$y, m$y+1.96*se$y, m$y-1.96*se$y,col='red',cex=2,type='b',add=TRUE)
Try inserting
par(fg = "red")
between your plot() and errbar() statements.
