Renaming Column Names in R Data Frames: A Simple Solution for Non-Standard Data Structures

The problem is with the rownames function not working as expected because the class of resSig is different from what it would be if it were a regular data frame.

To solve this, you need to convert resSig to a data frame before renaming its column. Here’s the corrected code:

# Convert resSig to a data frame
resSig <- as.data.frame(resSig)

# Rename the row names of the data frame to 'transcript_ID'
rownames(resSig) <- rownames(resSig)
colnames(resSig) <- "transcript_ID" # Add this line

# Write the table to a file
write.table(resSig, file = file.path(getwd(), "Downloads", 
    "ivan.txt"), row.names = FALSE, quote = FALSE)

Alternatively, you can use rownames_to_column from the dplyr package as shown in the updated code:

library(dplyr)

resSig <- resSig %>%
  as.data.frame() %>%
  rownames_to_column("transcript_ID")

This will achieve the same result without having to manually assign column names.
