It's interactive so after you callmerge_pdf
it wants a plot input. You input a blank space, hence the error. Try it like this (identical to yours but with a blank line removed):
library(plotflow)
library(ggplot2)
dat = data.frame(x=1:10, y=rnorm(10))
p1=ggplot(dat, aes(x,y)) + geom_line()
p2=ggplot(dat, aes(x,y)) + geom_line()
p3=ggplot(dat, aes(x,y)) + geom_line()
## Plot heights, widths
widths = c(9, 8, 10)
heights = c(5, 11, 6)
merge_pdf(length(widths), file = "test.pdf",
widths = widths,
heights = heights)
plot(p1)
plot(p2)
plot(p3)
