Deprecated {base} | R Documentation

## Deprecated Functions

### Description

These functions are provided for compatibility with older versions of R only, and may be defunct as soon as of the next release.

### Usage

    .Deprecated(new)
    .Alias(expr)
    reshapeWide(x, i = reshape.i,
                 j = reshape.j,
                 val = reshape.v,
                 jnames = levels(j))

    reshapeLong(x,jvars,  ilev = row.names(x),
                 jlev = names(x)[jvars],
                 iname = "reshape.i",
                 jname = "reshape.j",
                 vname = "reshape.v")

### Details

`.Deprecated("<new name>")` is called from deprecated functions. The original help page for these functions is available at `help("oldName-deprecated")` (note the quotes).

`.Alias` provided an unreliable way to create duplicate references to the same object. There is no direct replacement. Where multiple references to a single object are required for semantic reasons consider using environments or external pointers. There are some notes on http://developer.r-project.org.

`reshape*`, which were experimental, are replace by `reshape`. This has a different syntax and allows multiple time-varying variables. See `reshapeLong-deprecated` and `reshapeWide-deprecated` for the earlier syntax.
