I've used RODBC to read in ms access files... or if you're as lazy as
me you could use the following below (it can handle some other ms
office file types too and thinks it can recognize file types but as
has been pointed out in this list, using it with excel probably means
trouble)
read.mso <- function(fail, sheet="Sheet1$", browse=FALSE,
tables=FALSE, FUN = NULL, ...){
# require(RODBC)
# require(utils)
# 'fail' is Estonian for 'file', don't be confused :)
whence <- strsplit(basename(fail), "\\.")[[1]][2]
if(is.null(FUN)) FUN <- switch(whence, xls=odbcConnectExcel,
mdb=odbcConnectAccess, xlsx=odbcConnectExcel2007,
accdb=odbcConnectAccess2007, dbf=odbcConnectDbase,
identity)
con <- FUN(fail)
if(browse) browser()
res <- if(tables) sqlTables(con) else sqlFetch(con, sheet, ...)
close(con)
res
}
# lists tables with TABLE=TRUE, otherwise sqlFetch'es the table named in "sheet"
