Try this:
from rpy2 import robjects
robjects.r.ggsave(filename="x.pdf", plot=p, width=200, height=120, unit='mm')
Question
This gives me a plot and displays in on IPython:
from rpy2.robjects import pandas2ri
pandas2ri.activate()
from rpy2.robjects.lib import ggplot2
from rpy2.interactive import ipython
from pandas import DataFrame
dataf = DataFrame({"x":[1,4,5,2,4.5,3],"y":[3,2,6,2,4,2.1]})
p = ipython.ggplot(dataf) + \
ggplot2.aes_string(x = 'x', y = 'y') + \
ggplot2.geom_point() + \
ggplot2.geom_smooth(method = "loess")
p.png()
Now how do I save the plot to, say, pdf? In other words, is there an Rpy2 mapping for this?
ggsave(filename="x.pdf", plot=x, width=200, height=120, unit='mm')
Solution
Try this:
from rpy2 import robjects
robjects.r.ggsave(filename="x.pdf", plot=p, width=200, height=120, unit='mm')
