Covariate Analysis

[MarilynMil3s]

Hello! I had previously used NOISeq with covariates in the factor argument but now I am getting an error
` PrePost_noiseq<-
NOISeq::noiseq(
PrePost.UQ_batchCorrection2,
factor=c("Group", "Age"),
k=NULL,
norm = "n",
conditions = c("PRE","POST"),
pnr = 0.2,
nss = 5,
v = 0.02,
lc = 1,
replicates="no"

)
"Computing (M,D) values..."
Error in if (factor == i) { : the condition has length > 1`

is there any way to include covariates?

The covariates must be included in the NOISeq object you input to noiseq function. In your case, is PrePost.UQ_batchCorrection2 a noiseq object? If so, and the factors are well defined in that object, in argument factor, you just can pick up one factor at a time (either Group or Age, but not both). Please, read again the package documentation and let me know if it worked.
