One way would be to use the nls package:
library(nls)
foo.dat <- (0.83 * exp(-0.017 * 1:1000) + 0.5) + rnorm(1000,0,0.05) # your y values
foo.dat <- data.frame(cbind(foo.dat, 0:999)) # create some x values in a data frame
names(foo.dat) <- c("y", "x") # give them names
model <- nls( y ~ N * exp(
If you don't need the parameters in the curve, it seems like
library(modreg)
lines(supsmu(1:1000, foo.dat), lwd=3)
gives a very reasonable result.

Dear Luis,
You can use the pch argument to plot; assuming that class is numeric and
consists of single-digit integers, you could specify something like plot(
, pch=as.character(class)). If class is a factor, you could substitute
pch=as.character(as.numeric(type)).
