cbind.data.frame
Build Data Frame from Columns
Description
Build a data frame by combining vectors, existing
data frames, or matrices.
Usage
cbind.data.frame(..., deparse.level = 1)
Arguments
| ... |
either vectors, data frames, or matrices.
|
| deparse.level |
value determining the construction of labels (column labels
for cbind or row labels for rbind).
This applies only to unnamed vector (non-matrix) arguments.
- If deparse.level is 0, the corresponding row or column
has no label.
- If deparse.level is 1, the deparsed form is used
only if the argument is a simple name.
- If deparse.level is 2, the label is the deparsed
form of the argument.
Any other expression results in no label.
These are the only acceptable values for this argument.

Details
Calling this function is nearly equivalent to
calling data.frame.
See the help for data.frame for information
on other arguments to control the creation of row and column names, and so on.
This is a method for the generic function cbind.
Calling cbind when at least one argument
is a data frame is equivalent to
calling data.frame with the same arguments,
with the exception of the control arguments
check.names
and deparse.level.
Unlike data.frame, column names are not changed.
If you want variable names to be made unique,
call data.frame instead of cbind.
The argument deparse.level
(an argument to cbind) is ignored.
Names created correspond to deparse.level=1.
Value
returns a data frame formed using the vectors, the variables in the
data frames, or the columns of the matrices as variables.
returns the first row names of a data frame or
matrix encountered if row names are not supplied.

Examples
x <- data.frame(a=1:3)
cbind(1, x)
cbind(x,x) # variable names are "a", "a"
data.frame(x,x) # variable names are "a", "a.1"
