Hi
You might need an approach that converts the ggplot object to a gtable
and then either combine the gtables as here ...
http://stackoverflow.com/questions/16255579/how-can-i-make-consistent-width-plots-in-ggplot-with-legends
... or explicitly control the width of the plot within the gtable layout
as here ...

Hope that helps

Hello,
not totally sure if this is a R or a LaTeX topic...
I am a total newbie to R and LaTeX, and trying to write my masters
thesis right now... I tried to get this answered via
https://cran.r-project.org/web/packages/tikzDevice/vignettes/tikzDevice.pdf
...but I failed... :(
I am creating plots in R via ggplot2, and converting them to TeX
format via tikzDevice.
Now many of my plots have a legend on the right, which differs in size
(depending of course on the legend title and text).
If I now convert my Rplot using tikz() it only scales the size for the
whole image it creates.
What I want is: the rectangular plot itself to always be the same size
for all my plots (no matter how big/small the legend and the axis
numbers are)...
My Rscript with some test Data:
library(ggplot2)
library(scales)
require(grid)
library(tikzDevice)
#setting time zone
options(tz="Europe/Berlin")
tikz(file = "my_output_file.tex", standAlone=F,width = 6, height = 3)
cars['dt'] = seq(Sys.Date(),Sys.Date()-980,-20)
plot <- ggplot(cars,aes(y=speed,x=dist,color=as.integer(dt)))+
geom_point(size=2,alpha=0.7)+
xlab("distance")+
ylab("speed")+
scale_color_gradientn("dt",
colours=rainbow(6)
)+
#textsize
theme_bw()+
theme(legend.position="right",
legend.key.height=unit(2,"lines"),
legend.title=element_text(size=rel(0.8)),
legend.text=element_text(size=rel(0.8)),
axis.text.y=element_text(angle=90,
hjust=0.5),
axis.title=element_text(size=rel(0.8))
)
print(plot)
dev.off()
If I change now the legend text to a slightly longer text, the output
of course has a completely different plot-size.
Is there a way to maintain the plot size?
I hope somebody can help me, or lead me to the information I need...
