I am stumped:
Running the code
split <-sample.split(linear_reg$Height, SplitRatio = 0.7)
I get an error
Error in lenght(Y) : could not find function "lenght"
(spelling being incorrect come directly from RStudio)
I am not using the lenght / length function in my code at all.
Any idea what lenght(Y) refers to - especially since it is NOT defined or referenced in my code
