rpy2

问题 I am implementing rpy2 code in Django and when I convert pandas dataframe into r dataframe my app starts crashing and giving error: Error: C stack usage 60820464 is too close to the limit otherwise app works fine as long as i don't convert. Is there any problem/mistake in my code? My code snippet: from .models import Values import pandas as pd from rpy2.robjects import pandas2ri pandas2ri.activate() def rpyset(request): filterdata = pd.DataFrame(list(Values.objects.all().values('val1','val2',

问题 I'm trying to use ryp2 to do a logistic regression. I managed to execute it, but don't know how to extract the coefficients and p-values from the result. I don't want to print the values on the screen bu create a function to use them independently. import rpy2.robjects as ro mydata = ro.r['data.frame'] read = ro.r['read.csv'] head = ro.r['head'] summary = ro.r['summary'] mydata = read("http://www.ats.ucla.edu/stat/data/binary.csv") #cabecalho = head(mydata) formula = 'admit ~ gre + gpa + rank

问题 What is the equivalent of the following R code in Rpy2 in python? Var1 = c("navy", "darkgreen") names(Var1) = c("Class1", "Class2") ann_colors = list(Var1 = Var1) It's not clear what ann_colors is. When evaluated in R it gives: > ann_colors $Var1 Class1 Class2 "navy" "darkgreen" Is it an robject.ListVector ? I tried: robjects.ListVector({"Class1": "navy", "Class2": "green"}) but it's not quite it because I'm not sure how to tell the ListVector object that the name of this object is Var1 , i.e

问题 I'm looking to work on a SPSS files (.sav) using pandas . In the absence of the SPSS program, here's what a typical file looks like when converted to .csv: On investigation into what the first two rows signify (I don't know SPSS), it seems that the first row contains the Label s, while the second row contains the VarName s. When I bring the file into pandas thus: import pandas.rpy.common as com def savtocsv(filename): w = com.robj.r('foreign::read.spss("%s", to.data.frame=TRUE)' % filename) w

问题 I am a bit confused about how to install R (via compilation) as a shared library. The instructions here (Rpy2) say that I should do the following: # <go to the R source directory> make distclean ./configure --enable-R-shlib make make install but the first make ( make distclean ) would remove any previous installation of R under the same directory tree (e.g. the contents of the bin folder). What if I want to use the same installation for the R interpreter and the shared libraries? For example,

问题 I am having trouble installing the Python package rpy2. I have already compiled R as a shared library, but I do not have admin priviledges so I am trying to install rpy2 with: pip install -user rpy2 However, I am getting the following error: ./rpy/rinterface/_rinterface.c:86:31: fatal error: readline/readline.h: No such file or directory compilation terminated. error: command 'gcc' failed with exit status 1 I have downloaded readline to: /some/path/readline-6.2/ where I can see readline.h (I

问题 I am trying to calculate and generate plots using multiprocessing. On Linux the code below runs correctly, however on the Mac (ML) it doesn't, giving the error below: import multiprocessing import matplotlib.pyplot as plt import numpy as np import rpy2.robjects as robjects def main(): pool = multiprocessing.Pool() num_figs = 2 # generate some random numbers input = zip(np.random.randint(10,1000,num_figs), range(num_figs)) pool.map(plot, input) def plot(args): num, i = args fig = plt.figure()
