I have a collection of excel files which I am importing into
The files contain hidden data which I would like to disregard — eg, simply not importing it, or importing it with a flag indicating it was hidden so that I can then drop it.
The files contain two types of hidden data:
- Complete sheets are hidden
- Specific Rows within a sheet are hidden.
Is there a way to identify when data in excel is hidden?
Right now I am using the
gdata package, but am happy to use
XLConnect or other package
library(gdata) xlsfile <- "test.xls" # grab all the sheet names. # This is giving me both hidden & non-hidden sheets. I would like only the latter sheets <- sheetNames(xlsfile) # read in the xls file, by sheet xlData <- lapply(sheets, function(s) read.xls(xlsfile, sheet=s, stringsAsFactors = FALSE))
if needed, I can create a dummy
xls file and post it.
XLConnect has a nice function called
isSheetHidden which does what you want. Assuming
Sheet2 is hidden:
library(XLConnect) xlsfile <- "Book1.xls" wb <- loadWorkbook(xlsfile, create = TRUE) isSheetHidden(wb, "Sheet1") # FALSE isSheetHidden(wb, "Sheet2") # TRUE
gdata you would have to write your own function that calls the underlying perl package to access the sheet property, but it is possible.
