### linear regression with R in sagemath

Hi,

I know it is possible to do a linear regression directly inside sage. However, I was wondering if it was possible to call the lm function from R to do it as well. I tried the following code:

a =  r.lm(LLCCS00 ~ OILBRNP, data = reader)


LLCCS00 and OILBRNP are my two variables. They are in row. It is time series so for each variable, there is a value at each date (dates are columns). The issue I have is that I have a syntax error. I don't understand why.
