Description
Hi,
When I try to run the examples, I get this error message.
What should I do ?
Thanks in advance
s <- sticker(~plot(cars, cex=.5, cex.axis=.5, mgp=c(0,.3,0), xlab="", ylab=""),
+ package="hexSticker", p_size=20, s_x=.8, s_y=.6, s_width=1.4, s_height=1.2,
+ filename="inst/figures/baseplot.png")

Research direction
Start by reproducing the reported example call using sticker(~plot(cars, ...), package="hexSticker", filename="inst/figures/baseplot.png") and inspect the validGrob error and accompanying warnings. Check whether the failure is tied to the example, the plotting object, or the graphics environment. Done means the example runs successfully and creates the expected baseplot.png without the reported error.
