Edit Data Frames and Matrices

Description

Use data editor on data frame or matrix contents.

Usage

edit.data.frame(name, factor.mode=c("numeric", "character"),
                edit.row.names = any(row.names(name) != 1:nrow(name)),
                ...)
edit.matrix(name, edit.row.names = any(rownames(name)))

Arguments

Details

At present, this only works on simple data frames containing numeric or character vectors and factors. Factors are represented in the spreadsheet as either numeric vectors (which is more suitable for data entry) or character vectors (better for browsing). After editing, vectors are padded with NA to have the same length and factor attributes are restored. The set of factor levels can not be changed by editing in numeric mode; invalid levels are changed to NA and a warning is issued. If new factor levels are introduced in character mode, they are added at the end of the list of levels in the order in which they encountered.

Value

The edited data frame.

Note

fix(dataframe) works for in-place editing by calling this function.

If the data editor is not available, a dump of the object is presented for editing using the default method of edit.
