我有以下一段代码，该代码用于从名为RawData的目录中获取4个csv文件，并使用rbind合并行，效果很好

library(data.table)

setwd("C:/Users/Gunathilakel/Desktop/Vera Wrap up Analysis/Vera_Wrapup_Analysis/RawData")  

myMergedData <- 
  do.call(rbind,lapply(list.files(path = getwd()),fread))

但是，我想确保此代码在另一台计算机上可重现，并决定放弃setwd。因此，我决定使用here包并执行相同的过程

library(here)


myMergedData <- 
  do.call(rbind,lapply(list.files(path = here("RawData")),fread))

当我运行上面的脚本时，它会显示以下消息
