I am conducting a meta-analysis using the metafor package. In the forest function, I was not able to create a systematic bar and tick marks at the base of forest plot for relative risk scale (such as 0.25, 0.5, 1, 1.5) without changing it to a log scale when I used "atransf = exp" to show risk estimates in normal scale.
forest(meta_a, atransf=exp, xlim = c(-5,2.5), ylim = c(-2,16.5)) - gave me a random tick marks and scale.
I needed to add "at = log (c(0.25,0.5,1,2))" in the forest function to get a systematic bar and tick marks at 0.25, 0.5,1,2 but they are in log scale while the risk estimates are not in log scale. I do not want to show the risk estimates in the log scale.
Help is greatly appreciated.
