year 0.018121 0.009951 1.821 0.106
Residual standard error: 0.09039 on 8 degrees of freedom
Multiple R-Squared: 0.293, Adjusted R-squared: 0.2047
F-statistic: 3.316 on 1 and 8 DF, p-value: 0.1061
which means that there is no evidence for linear trend
lining up << all those "o"'s >> does not mean anything
