Dear R users,
I am new user for elastic net. I am trying to use elasticnet
library.
I have marker data with 359 markers and 168
samples, and response is metabolites. I am trying to do regression
between
a metabolite and markers.
But i am getting the following error:
en<-
enet(marker,as.numeric(vio),lambda=0.5,normalize=FALSE,intercept=TRUE)
Error in one %*% x : requires numeric matrix/vector
arguments
Then, I convert marker into numeric by using the following
command. And, here also getting error.
as.numeric(marker)
Error: (list) object cannot be coerced to type
'double'
is.numeric(marker)
[1] FALSE
Alternatively, I converted marker into numeric by using
data.frame command, it seems markers are now converted into numeric.
is.factor(datafram01[,1])
[1] FALSE
is.numeric(datafram01[,1])
[1] TRUE
But when i did again elastic net, i got the same error:
en<-
enet
(datafram01,as.numeric(vio),lambda=0.5,normalize=FALSE,intercept=TRUE)
Error in one %*% x : requires numeric matrix/vector
arguments
Does someone have ideas to overcome these problem?
If it is, it will be great help for me.
Thanks in advance.
Sincerely,
