An example on how to use dput - got this from Hadley http://goo.gl/5BGlW

dput_example.R

#assume you have a data set represented by an object called BOD (BOD is actually a dataset internal to R). then run dput with that data object
dput(BOD)
#the ouput of this function will be the representation of that data set: structure(list(Time = c(1, 2, 3, 4, 5, 7), demand = c(8.3, 10.3, 19, 16, 15.6, 19.8)), .Names = c("Time", "demand"), row.names = c(NA, -6L), class = "data.frame", reference = "A1.4, p. 270")
#when you want to request help, just start the reproducible example by throwing the output of dput into a data object:
BOD  <- structure(list(Time = c(1, 2, 3, 4, 5, 7), demand = c(8.3, 10.3, 19, 16, 15.6, 19.8)), .Names = c("Time", "demand"), row.names = c(NA, -6L), class = "data.frame", reference = "A1.4, p. 270")
#from here on then just write the code you wrote and the corresponding error message
