Read Excel file into R with XLConnect package from URL

Question

There are lots of good examples out there on how to read Microsoft Excel files into R with the XLConnect package, but I can\'t find any examples of how to read in an Excel f

Answer 1

library(relenium)
library(XML)
library(RCurl)

firefox=firefoxClass$new()
url="https://www.misoenergy.org/Library/Repository/Market%20Reports/20140610_sr_nd_is.xls"
url=sprintf(url)
firefox$get(url)

This will open a Firefox instance within R and ask you to download the file, which you could then open in the next line of code. I don't know of any R utilities that will open an excel spreadsheet from HTTPS.

You could then set a delay while you're saving the file and then read the sheet from your downloads folder:

Sys.sleep(10)
sheet <- c("Sheet1")
data  <- readWorksheetFromFile(path, sheet, header=TRUE, startRow=11, startCol=2, endCol=13)
