[R-meta] Meta package - Bubble plot subgroup colours

[dirk@richter m@ili@g off upd@u@ibe@ch]

Dear Gerta

Many thanks for your suggestion. The code that finally worked looked like this:

cols<- (Fleiss93cont$region=="Europe")+1
bubble(mr2, col = cols, bg = cols)

It seems that the colours are by default set to red and black. Is there any chance to change from red to, say, grey? Publishers often prefer non-coloured graphs.

Best wishes,
Dirk

Dear Dirk,

Try code like this one:

# Load library
library(meta)

# Look at example for bubble plot, particularly mr2 (meta-regression with age as covariate)
example(bubble)

# Look at the other covariate (region)
Fleiss93cont$region

# Define colors (here only 2, black and red) cols <- (Fleiss93cont$region=="Europe") + 1

# Make a coloured bubble plot
bubble(mr2, lwd=2, col.line="blue", xlim=c(50, 70), col = cols, bg = cols)

Best,

Gerta
