Hi,
I am trying to do a lasso regression using the lars package with the
following data (see attached):
Nothing attached. (And now you have also sent an exact duplicate.)
snipped failed attempt to include data inline that was sabotaged by
using HTML mail
#load Data
crs<- read.csv("file:///C:/temp/Horse//horseracing.csv<file:///C:\temp\Horse\horseracing.csv
>", na.strings=c(",", "NA", "", "?"), encoding="UTF-8")
This looks wrong. Your data had no commas in it and you are also
setting na.strings to include commas. If I am wrong then you should
provide dput on crs instead of
# # define x and y
x= x<-crs[,9] #predictor variables
y= y<-crs[1:8,] #response variable
library(lars)
cv.lars(x, y, K=10, trace=TRUE, plot.it = TRUE,se = TRUE,
type="lasso")
and I get:
LASSO sequence
Error in one %*% x : requires numeric/complex matrix/vector arguments
Any idea on what I am doing wrong? Thank you!!
Sincerely,
tom
