if condition and for cycles
I have two questions about R: 1) Does anyone knows why I get the plots but not the summary results of the linear fitting when I run this code? When I run it outside the if condition it works fine. if (op==4) { t=1:length(time(SeaIce)) fitlinear=lm(SeaIce~t) windows() plot.ts(SeaIce) lines(ts(fitlinear$fitted.values,start=1979,frequency=12)) summary(fitlinear)
