Dear Alok Patra

As mentioned by Qamar Ul Islam , I suggest using the UniprotR package and its function GetNamesTaxa().

Best wishes,

Francesco

Try Biomartr

# Install core Bioconductor packages if (!requireNamespace("BiocManager")) install.packages("BiocManager") BiocManager::install()

# Install package dependencies BiocManager::install("Biostrings", version = "3.8") BiocManager::install("biomaRt", version = "3.8")

# install biomartr 0.9.0 install.packages("biomartr", dependencies = TRUE)
