checkNames {DiceKriging} | R Documentation |
Consistency test between the column names of two matrices
Description
Tests if the names of a second matrix are equal to a given matrix up to a permutation, and permute its columns accordingly. When the second one has no column names, the names of the first one are used in the same order.
Usage
checkNames(X1, X2, X1.name = "X1", X2.name = "X2")
checkNamesList(X1, l2, X1.name = "X1", l2.name = "l2")
Arguments
X1 |
a matrix containing column names. |
X2 |
a matrix containing the same number of columns. |
l2 |
a list with length |
X1.name |
, |
X2.name |
optional names for the matrix |
l2.name |
optional names for |
Details
If X2
does not contain variable names, then the names of X1
are used in the same order, and X2
is returned with these names. Otherwise, if the column names of X1
and X2
are equal up to a permutation, the column of X2
are permuted according to the order of X1
' names.
Value
The matrix X2
, with columns possibly permuted. See details.

Examples
X1 <- matrix(1, 2, 3)
X2 <- matrix(1:6, 2, 3)
colnames(X1) <- c("x1", "x2", "x3")
checkNames(X1, X2)
# attributes the same names for X2, and returns X2
colnames(X2) <- c("x1", "x2", "x5")
## Not run: checkNames(X1, X2)
# returns an error since the names of X1 and X2 are different
colnames(X2) <- c("x2", "x1", "x3")
checkNames(X1, X2)
# returns the matrix X2, but with permuted columns
l2 <- list(x3 = 1, x2 = c(2, 3), x1 = -6)
checkNamesList(X1, l2)
