Answer 1

XLConnect does not support importing directly from URLs. You have to use e.g. download.file first to download the file to your local machine:

require(XLConnect)
tmp = tempfile(fileext = ".xls")
download.file(url = "http://www.econ.yale.edu/~shiller/data/chapt26.xls", destfile = tmp)
readWorksheetFromFile(file = tmp, sheet = "Data", header = FALSE, startRow = 9, endRow = 151)

or with your originally proposed URL:

require(XLConnect)
tmp = tempfile(fileext = ".xls")
download.file(url = "https://www.misoenergy.org/Library/Repository/Market%20Reports/20140610_sr_nd_is.xls", destfile = tmp, method = "curl")
readWorksheetFromFile(file = tmp, sheet = "Sheet1", header = TRUE, startRow = 11, startCol = 2, endCol = 13)
