In DavZim/colorTable:

Description

Checks that a vector has a given lengths, if x is null or NA, the default is repeated a given amount

Usage

check_and_rep(x, req_size, default = "white", name = "x")

Arguments

x	a vector, a matrix, or a data.frame
req_size	a required size of x (a single value for a vector or a vector of 2 values)
default	default values if x is NULL/NA
name	a name of x (for the error message only)

Value

a vector of size req_size or a matrix (if req_size has length 2)

Examples

# vector
check_and_rep(NA, 3, "red")
check_and_rep("green", 3, "red")
## Not run: 
    # produces an error
    check_and_rep(c("red", "green"), 3, "red")
    # change the name of x
    check_and_rep(c("red", "green"), 3, "red", "fancy_vector")

## End(Not run)
check_and_rep(c("red", "green", "blue"), 3, "red")

# Matrix
check_and_rep("green", c(2, 3), "white")

x <- matrix(c("red", "green", "blue", "yellow"), 2, 2)

check_and_rep(x, c(2, 2), "white")
