It first come with the error：
Error in FEAST(C = otus, metadata = metadata, EM_iterations = 1000, COVERAGE = NULL, :
The metadata file must contain an 'id' column matching the source environments for each sink sample.
after that, i manually added the id in your file metadata_example.txt，and it comes with the mentioned error：
Error in rowSums(C[c(train.ix, test.ix), ]) :
'x' must be an array and must have at least two dimensions
I have no idea how to continue this work. I don't know if it's a configuration problem with my R.
Does anyone have insight on what could be causing this error?
I am try FEAST with the example dataset https://github.com/cozygene/FEAST/tree/master/Data_files and have hindered with the error： Error in rowSums(C[c(train.ix, test.ix), ])
my steps here is :
Packages <- c("Rcpp", "RcppArmadillo", "vegan", "dplyr", "reshape2", "gridExtra", "ggplot2", "ggthemes") lapply(Packages, library, character.only = TRUE) metadata <- Load_metadata(metadata_path = "./FEAST-master/Data_files/metadata_example.txt") otus <- Load_CountMatrix(CountMatrix_path = "./FEAST-master/Data_files/otu_example.txt")
