Forest plot - error #167

Open MaVdb opened 4 years ago

MaVdb commented 4 years ago

I would like to create a forest plot of the MR results of 1 exposure on 1 outcome, showing the OR and CI for different tests (ivw, Egger, weighted median...).

However, I am unable to create a forest plot:

res <- mr(dat) forest_plot(res)

==> Error in $<-.data.frame(*tmp*, "lab", value = 1L) : replacement has 1 row, data has 0

res is a dataframe containing the following columns: id.exposure, id.outcome, outcome, exposure, method, nsnp, b, se, pval

Hi Cynthia,

I did not solve the problem. I've plotted the forest plot in R, without any package, by entering the output of the association tests manually.

Best, Marijne

I have the same problem, did you find any solutions? I am considering using "forestplot" package to do this, but I am not sure if it works.
