# Are R-squared and F the same for variables in Multiple Regression in R

I ran a multiple regression analysis and got significant results for lFreq, Len variables, and interaction lFreq x Len. Now I need to report these results and I am a bit confused whether F(7, 924) = 9.876 and R^2= 0.06961 stand for all variables? It seems to me that each variable should have its own F and R^2 values... How should I calculate them?

Call:
lm(formula = duration ~ lFreq * Len * group, data = df.eyes)

Residuals:
Min        1Q    Median        3Q       Max
-0.079878 -0.010185 -0.001281  0.009893  0.192742

• Correct. In fact, there is an easy relation between $R^2$ and this $F$-statistic that tests the significance of the regression model: $R^2=kF/(kF+n-k-1)$, where $k=7$ is the number of regressors in the model and $n=931$ is the number of data points. – StijnDeVuyst Aug 22 '15 at 17:47
