Hello,
I've encoured some difficulty with using RPy to generate a plot
showing the results of a linear regression. My code is as follows:
r = robjects.r
xVec = robjects.FloatVector(X)
yVec = robjects.FloatVector(Y)
robjects.globalEnv["xVec"] = xVec
robjects.globalEnv["yVec"] = yVec
reg = r.lm("xVec ~ yVec")
print(r.summary(reg))
r.plot(xVec, yVec, xlab="Northing", ylab="Normalized Unique Sequences")
r.abline(reg, lty=1)
This all works except the last line. My resulting plot shows my data
points, but not the regression line. Has anyone encountered this
problem before? Thanks for any and all help. I'm new to RPy\R so
perhaps am missing something simple here.
Cheers,
Donovan
PS: Thanks for your help Laurent on accessing the adj. r-squared value.
