I'm trying to make a linear regression between PM10 and Ref for each of the
four WR, I've tried this:
plot(Nord$PM10 ~ Nord$Ref, main="Nord", xlab="Ref",
ylab="PM10")
but it does not work, because "Nord cannot be found"
what was wrong? how can I do it? please help me

your dataframe needs to be called "Nord". If it is not, then replace "Nord" with the actual name of your dataframe On Sat, Aug 13, 2011 at 10:43 PM, maggy yan <kiotoqq at googlemail.com> wrote:> dear R users, > my data looks like this > > ? ? ? ?

Hi:
Try something like this, using dat as the name of your data frame:
xyplot(PM10 ~ Ref | WR, data = dat, type = c('p', 'r'))
The plot looks silly with the data snippet you provided, but should
hopefully look more sensible with the complete data. The code creates
a four panel plot, one per direction, with points and a least squares
regression line fit in each panel. The regression line is specific to
a data subset, not the entire data frame.
HTH,
Dennis
