Keep rows in a dataset if one value in a column is duplicated
...keep the pair observations, and was using the code below
until it gave me the error " $ operator is invalid for atomic vectors". I am
just beginning to learn R, so I apologize if the code is really rough.
Basically I want to keep all the rows in the data set for which the value of
"Pairiddups" is TRUE. How do I do it? And how do I get past the error?
Thank you so much,
Diana

multiple fitted curves plot
Dear Rusers,
How would I plot several (24) fitted curves (nonlinear least squares)
within a single plot? To get the parameters I use:
resff <- list()
for (s in levels(PairID)) {
resff[[s]] <- nls(Photo ~ SSasymp(Ci, Asym, lrc, c0),
subset = (PairID == s))
}
Is it also possible to plot two different groups (male, female) of curves
in the same plot, with different style lines?
Many thanks,
Stewart
