Hi I'm having the exact same problem as Mellisaszy. I get the same issue when I run the example data and when I run my own data.
Error message: Error in FEAST(C = data.asv.bac.dna, metadata = metadata, different_sources_flag = 1, : 'list' object cannot be coerced to type 'integer'
R version 4.3.1, FEAST_0.1.0
str(metadata) 'data.frame': 45 obs. of 3 variables: $ Env : Factor w/ 6 levels "air","SBW","seaice",..: 1 1 1 1 1 1 1 1 1 1 ... $ SourceSink: chr "Sink" "Sink" "Sink" "Sink" ... $ id : int 1 1 1 1 1 1 1 1 1 1 ...

Does anybody have a solution to this?
Best regards, Marie
Hello all! I have the same issue as both commenter above and can't figure out the reason. I made sure all data is factors or integer and formatted the same way as in the examples. In my ASV file, the column names are the sample name, but I get the same error if I transpose the matrix or add a SampleID column (it's a character string). Thanks for your help!
`path="~/stats/FEAST/bac/FEAST_to_sessile"
FEAST_output <- FEAST(C = asv, metadata = feast_meta, different_sources_flag = 0)`
Hello! I am having the exact same problem. First, I wanted to confirm that the row names for both the otu table and the sample metadata need to be the sample id names? On the main page the otu table has taxa as rows and sample id's as columns, but I keep seeing online that it is the opposite that works.
Second, if the case is that the columns all need to be intergers... how can we do that when the example data has characters?
Hopefully I can clarify some of the issues discussed in this thread:
Note that the Load_CountMatrix function transposes the table, which is why the example data is flipped from what is required for the FEAST function to run. (The Load_metadata function does not transpose data).
Good luck and please let me know if there is still any confusion.
A colleague and I had to add a 'SampleID' column to the meta data table to make it work. The column is the name of each samples, which confusingly, also needs to be the row name. We ended up with 4 columns in the metadata files. It doesn't seem to be what is written in the help files, but it worked for us. Let me know if you have any more questions! Here is what my data looks like
Hey! Thanks for the help everyone! My mistake turns out to have been due to a real rookie move.... My count matrix was a data frame, not a matrix... thank you so much for your help!
Hello,
sorry for the potentially amateur question.
this is what i have:
str(otus) 'data.frame': 2139 obs. of 175 variables: $ LF004d: int 0 0 0 0 0 0 0 0 0 0 ... $ LF004e: int 0 0 0 0 0 0 0 0 0 0 ... $ LF005c: int 0 0 0 0 0 0 0 0 0 0 ... $ LF005d: int 0 0 0 0 0 0 0 0 0 0 ... $ LF005e: int 0 0 0 0 0 0 0 0 0 0 ... $ LF006a: int 0 0 0 0 0 0 0 0 0 0 ... [list output truncated]
str(metadata) 'data.frame': 175 obs. of 4 variables: $ SampleID : chr "LF004d" "LF004e" "LF005c" "LF005d" ... $ Env : chr "d" "e" "c" "d" ... $ SourceSink: chr "Source" "Source" "Source" "Source" ... $ id : chr "NA" "NA" "NA" "NA" ...
metadata$id contains numbers from 1 to 15 (I have 15 different sinks) and NA (for all sources)
i am trying the FEAST function: FEAST_output <- FEAST(C = otus, metadata = metadata)
this is the error message: Error in FEAST(C = otus, metadata = metadata2) : 'list' object cannot be coerced to type 'integer'
I am not sure how to proceed. Is the issue with metadata$id? i attempted to make metadata$id numeric by typing: metadata$id<-as.numeric(metadata$id)
but the same error message results.
thank you so much for your help.
Sincerely, Melissa
