xl
Data exchange with running Microsoft Excel instance.
xl, xlc, xlr, xlrc objects are already defined in
the package. It doesn't need to create or init them. Just after attaching
package one can write something like this: xl[a1] = "Hello, world!"
and this text should appears in A1 cell on active sheet of active
Excel workbook. xl(*)n family of functions creates new worksheet for
output. You can provide sheet name and position via
xl.sheet.name/before.
Usage
# S3 method for xl
[(x, str.rng, drop = !(has.rownames(x) | has.colnames(x)),
na = "", ...)# S3 method for xl
[[(x, str.rng, drop = !(has.rownames(x) | has.colnames(x)),
na = "", ...)
# S3 method for xl
$(x, str.rng)
# S3 method for xl
[[(x, str.rng, na = "", ...) <- value
# S3 method for xl
$(x, str.rng) <- value
# S3 method for xl
[(x, str.rng, na = "", ...) <- value
# S3 method for xln
[[(x, str.rng, na = "", xl.sheet.name = NULL, before = NULL,
...) <- value
# S3 method for xln
$(x, str.rng) <- value
# S3 method for xln
[(x, str.rng, na = "", xl.sheet.name = NULL, before = NULL,
...) <- value
xl.selection(drop = TRUE, na = "", row.names = FALSE, col.names = FALSE,
...)
Arguments
- x
One of
xl,xlc,xlr,xlrcobjects.xl- read/write with/without column and row names, "r" - with rownames, "c" - with colnames- str.rng
character Excel range. For single bracket operations it can be without quotes in almost all cases.
- drop
logical. If TRUE the result is coerced to the lowest possible dimension. By default dimensions will be dropped if there are no columns and rows names.
- na
character. NA representation in Excel. By default it is empty string.
- ...
additional parameters. Not yet used.
- value
suitable replacement value. It will be recycled to fill excel range only if it is object of length 1. In other cases size of excel range is ignored - all data will be placed in Excel sheet starting from top-left cell of submitted range.
- xl.sheet.name
character. sheet name in active workbook (for
xl(*)n).- before
character/numeric. sheet name or sheet number in active workbook before which new sheet will be added (for
xl(*)n).- row.names
logical value indicating whether the Excel range contains the row names as its first column.
- col.names
logical value indicating whether the Excel range contains the column names as its first row.
Details
xl object represents Microsoft Excel application. For
convenient interactive usage arguments can be given without quotes in most
cases (e. g. xl[a1] = 5 or xl[u2:u85] = "Hi" or
xl[MyNamedRange] = 42, but xl["Sheet1!A1"] = 42). When it
used in your own functions or you need to use variable as argument it is
recommended apply double brackets notation: xl[["a1"]] = 5 or
xl[["u2:u85"]] = "Hi" or xl[["MyNamedRange"]] = 42.
Difference between xl, xlc, xlrc and xlr is
xl ignore row and column names, xlc suppose read and write to
Excel with column names, xlrc - with column and row names and so on.
There is argument drop which is TRUE by default for xl
and FALSE by default for other options. xl.selection returns
data.frame with data from current selection in Excel.
All these functions never coerce characters to factors
Value
Returns appropriate dataset from Excel.
