Indeed!

Hello,
I'm trying to annotate my plots nicely and am running into trouble.
This example contains two problems:
a) the 'text()' arguments do not show the conditional behavior I'm
trying to give them. I try to test for the intercept of my regression
and reformat the output accordingly ('+
I have a data frame. And I'd like to subset according to rownames.
subset(mydataframe, rownames(mydataframe) == myrow, select = mycols)
it turned out that myrow cannot be a vector. But I have multiple rows to
pick. Is there a way to get around this problem??
Thank you for your help!!
