checkNumVec: Checking if all elements of a list are all numeric vectors

Description

Checking if all elements of a list are all numeric vectors

Usage

checkNumVec(listNum, namesListElements = NULL)

Arguments

listNum

A list of the vectors of which one wishes to check if their data type is numeric

namesListElements

Character vector containing the names of the variables of which the data type is checked. Optional parameter, with as default value NULL. This argument should be used when the variable of which the data type is checked is not an object that was provided as an argument to the function, or when the list elements of the first argument do not have a name attached to it.

Value

No value is returned if all vectors have the numeric data type. If not, an error message is thrown for each element of the list that does not pertain to the numeric data type.

Examples

# NOT RUN {
arg1 <- 2
checkNumVec(list(arg1))

# }
# NOT RUN {
checkNumVec(list(TRUE, T, 2))
checkNumVec(list(TRUE, T, 2), c('Var1', 'Var2', 'Var3'))

arg2 <- 0.8
checkNumVec(list(arg2))
checkNumVec(list(arg2, 'T', 2))
# }
