Python 保存rpy2.robjects.lib.ggplot2

这将为我提供一个绘图，并在IPython上显示：

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()

现在，我如何将绘图保存到（比如）pdf？换句话说，是否有Rpy2映射

ggsave(filename="x.pdf", plot=x, width=200, height=120, unit='mm')

试试这个：

from rpy2 import robjects
robjects.r.ggsave(filename="x.pdf", plot=p, width=200, height=120, unit='mm')
