[R] removing intercept from lm() results in oddly high Rsquared

Can anyone help me understand why an lm model summary would return an
r.squared of ~0.18 with an intercept term, and an r.squared of ~0.98
without the intercept? The fit is NOT that much better, according to
plot.lm: residuals are similar between the two models, and a plot of
observed x predicted is almost identical.
Thanks,
-Joseph
