equivalent of scale_size_area in rpy2 for ggplot2 in Python? -


does rpy2 have equivalent of scale_size_area() ggplot2? if not, how can write it? i'm referring function:

http://docs.ggplot2.org/0.9.3/scale_size_area.html

i scale points size according area, not radius believe default.

no, rpy2 not have feature since ggplot2 wrapper module hand coded. (hopefully, author notes metaprogramming used make code shorter , more automatic.) however, news is not hard add own feature. here's how add scale_size_area() existing functionality:

import rpy2.robjects.lib.ggplot2 ggplot2 import rpy2.robjects ro  mtcars = ro.r('mtcars') gp = ggplot2.ggplot(mtcars) pp = gp + ggplot2.aes_string(x='wt', y='mpg', size='cyl') + ggplot2.geom_point()  # using standard size (radius) aesthetic size pp.plot()  # create scalesizearea (based on ggplot2.py in rpy2) class scalesizearea(ggplot2.scalesize):     _constructor = ggplot2.ggplot2_env['scale_size_area']  ggplot2.scale_size_area = scalesizearea.new  # can use scale_size_area instead! pp_area = pp + ggplot2.scale_size_area() pp_area.plot()

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
