[R-meta] increase axis text size in funnel plot

Fri, Sep 8, 2023 4:55 AM

Dear Sicong,

To adjust the size of the axis text and tick labels, use 'cex.axis' and 'cex.lab'.

For example:

dat <- escalc(measure="RR", ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat.bcg)
res <- rma(yi, vi, data=dat)

funnel(res)
funnel(res, cex=2)
funnel(res, cex=2, cex.axis=1.5, cex.lab=1.5)

To adjust the legend size, you will need the development version of metafor:

https://wviechtb.github.io/metafor/#installation

Then the 'legend' argument allows more flexibility. For example:

funnel(res, legend=TRUE)
funnel(res, legend=list(cex=2))

'cex' can even take on three different values, the first for the text, the second for the boxes, the third for the points. Like this:

funnel(res, cex=2, legend=list(cex=c(2,3,1)))

And to create 'composite figures', you can use:

par(mfrow=c(2,2))
funnel(res)
funnel(res, cex=2, cex.axis=1.5, cex.lab=1.5)
funnel(res, legend=TRUE)
funnel(res, cex=2, legend=list(cex=c(2,3,1)))

Best,
Wolfgang

Dear Michael,

My apologies for missing important details. I was using metofor and please see my
current codes below for getting the composite figure:

jpeg("../figure/funnel.jpeg", width = 1600, height = 1920, units = "px", quality
= 100)
par(mfrow=c(3,1))
metafor::funnel(rma(d, vi =  dv_LOR2g, method = "REML", data = aggr_btwES_pt),
xlab = "Effect Size (d)", level = c(90, 95, 99), shade=c("white", "gray55",
"gray75"), legend = F, addtau2 = T, cex = 1,  at = c(-5, 0, 5))
metafor::funnel(rma(d, vi =  dv_LOR2g, method = "REML", data = aggr_btwES_hc),
xlab = "Effect Size (d)", level = c(90, 95, 99), shade=c("white", "gray55",
"gray75"), legend = F, addtau2 = T, cex = 1)
metafor::funnel(rma(d, vi =  dv_LOR2g, method = "REML", data = aggr_btwES), xlab
= "Effect Size (d)", level = c(90, 95, 99), shade=c("white", "gray55", "gray75"),
legend = F, addtau2 = T, cex = 1)
dev.off()

Thank you!

Cheers,

Dear Sicong

There are many, many packages on CRAN which generate forest plots, some
as standalone facilities and some as part of genral meta-analysis
software, so unless you give us more detail about which package you are
using and what happened when you tried we are unlikely to be able to be
of much help.

Dear All,

I have run into some difficulties when making a figure consisting of multiple

funnel plots, while trying to minimize figure post-processing. It would be great
to hear any suggestions for the questions below:

   *   1. How to specifically adjust the size of the axis text and tick labels?

I hope to find an argument like ?size? in ggplot to achieve it.

   *   2. How to specifically increase the size of the funnel plot legend?
   *   3. Is there a way to create a composite figure in a way similar to

?ggarrange? in ggplot when having multiple funnel plots?

Thank you in advance!
