Hi R team,
I can use rio package to read excel file into R as a list. The excel file
content multiple sheets (30 - 40 data sheets). I can convert each data elements
into dataframe manually. I have multiple excel files with multiple data sheets.
I need to load them into R and do the comparison for same sheet name from
difference excel file. My current code is:
 library(rio)? ?setwd ("C:/temp")
filenames <- gsub("\\.xlsx$","",
list.files(pattern="\\.xlsx$"))
for(i in filenames){
? assign(i, import_list(paste0(i, ".xlsx", sep="")))
}
file1_dx1? ? ?<-? file1[["dx1"]]

file1_dx2? ? ?<-? file1[["dx2"]]

file1_dx3? ? ?<-? file1[["dx3"]]

file2_dx1? ? ?<-? file1[["dx1"]]

file2_dx2? ? ?<-? file1[["dx2"]]
......

I hope the code can?automatic converting the list (may have 30 - 40 lists) by
adding file name (such as: filename_sheetname) and put it in for loop


Thank you,
Kai
