Subject: [R] problem with the behaviour of dashed lines in R plots

Hi,
Sarah's last comment about using min/max x got me thinking. It's not that
the points are "very close together", it's that the x-values are not
ordered. So the plot is actually drawing a dashed line back-and-forth
between different points on the line, which has the effect of making the
result ap
hi Sarah,
Thanks a lot for having taken time to answer me and for your reply. I
wonder how I missed this solution. Indeed plotting the line with the 2
extreme data points works perfectly.
Best,

Hi,
It's because you are plotting a line between each of the points in
your data frame, and they are very close together:

dear R users,
I am performing a linear regression with lm, and I would like to plot
the regressor in dashed lines. I know that the lty=2 option is the way
out, but it has a very strange behaviour: the line starts dashed but
then the spaces between each dash becomes very tiny and so the line
