Error: could not find function "read.DNAStringSet" [closed]

Question

This is very awkward. I use BSgenome to write a DNAStringSet fasta file,

writeXStringSet(DNAcutout1.seq, "DNAcutout1.fa", append=FALSE,
compress=FALSE,compression_level=NA, format="fasta")

but when I run another function, it is said

library(NuPoP)
predNuPoP("DNAcutout1.fa", species=5, model=4)
[1] "The input file is not in FASTA format, or contains characters other than A/a,
C/c,G/g, T/t, N/n, stop!"

so I wanna read it back to see what goes wrong, but I can't use read.DNAString

read.DNAStringSet(file="DNAcutout1.fa", format="fasta")
Error: could not find function "read.DNAStringSet"

Please HELP! Thank you

Answer 1

As I mentioned in the comments. read.DNAStringSet has been renamed to readDNAStringSet. Use the latter function name instead
