Hi all,
Do I need to define limits as the error message seems to suggest?
The error message, my code, the output and the first few lines of my
data are all below.
Thank you!
"Error in Getlim(at, allow.null = TRUE, need.all = TRUE) :
variable dmodel.df does not have limits defined in fit or with
datadist"
My code:
==================
library(Hmisc); library(Design); library(lattice);
= read.table("./data_cub3.txt", header=TRUE, nrows=100)
f <- ols(dmodel.df$y1 ~ rcs(dmodel.df$x1,3) )
print(f)
dd <- datadist(dmodel.df$x1)
Try instead:
dd <- datadist(dmodel.df)
f <- ols( y1 ~ rcs(x1,3), data=dmodel.df )
options(datadist="dd")
describe(dmodel.df)
print( Function(f) )
plot(dmodel.df$x1, dmodel.df$y1)
plot(f, add=TRUE, col="blue", pch=2)
Output:
