[R] lm without intercept, false R-squared

[Christof Kluß]

for example the same model with intercept R² = 0.6, without intercept R²
= 0.9 and higher. In my definition of R², R² has to be equal or less
without intercept

I do not know what R shows, but in the summary of the model without
intercept it does not show the R² of the regression line.

When I run a regression I like to have the R² of the regression line and
not something else. ;)
