I am using metafor to create forest plots. This code gives me the

1, 10)), slab=forest$SNP, atransf=exp)
As does this (setting colors):
forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, col=c(1,2,3),
slab=forest$SNP, atransf=exp)
But if I try to set both 'at' and 'col':
forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, col=c(1,2,3),
at=log(c(.05, .25, 1, 10)), slab=forest$SNP, atransf=exp)
I receive this error:
Error in polygon(x = c(alim[2], alim[2] - (1.4/100) * cex * (xlim[2]
- :
formal argument "col" matched by multiple actual arguments
Any help greatly appreciated.
Can you reproduce this using the examples in the package help pages?
