How to speedup write.xlsx process of excel in R

Question

I am in need of writing my output to an excel file in R . The t_content has around 401104 rows and 200 columns .

write.xlsx(t_content, paste0("../output/",'Content.xlsx'),
           col.names = T, append = TRUE)

This command takes a very long time to complete the task. Any other alternative way?

Answer 1

您可能想尝试writexl包中的write_xlsx() 。

writexl::write_xlsx(t_content, paste0("../output/",'Content.xlsx'))

Answer 2

data.table::fwrite命令非常快，可以向您显示进度条，但它会为您提供一个 .csv 文件，然后可以与 excel 一起使用。
