LJexm

LJexm is an R package designed to automate the process of extracting ZIP files, converting ‘Word’, ‘Excel’, and ‘HTML/HTM’ files to PDFs, and merging PDF files in a structured order.

Installation

To install LJexm from source, run:

# Install from source  
install.packages("LJexm", repos = NULL, type = "source")  

Usage

Error Handling

• Errors and status messages are logged in conversion_log.txt during execution.
  
• After processing, messages are printed using message() in R.

Manually Checking Errors (If Needed)

If you need to check errors manually before running the script, you can view the log file:

log_file <- file.path("path/to/your/folder", "conversion_log.txt")  
if (file.exists(log_file)) {  
  log_content <- readLines(log_file)  
  message(log_content, appendLF = TRUE)  
}
