Apply a function over a list or vector with optional silence

This function is a wrapper around the base base::lapply function that allows for the application of a function over a list or vector. It optionally allows for the suppression of the function's return value, making it useful for operations where the user is only interested in the side effects of the function.

Usage

lapply_(X, FUN, Silent = TRUE, ...)

Arguments

X

A list or vector. The input data over which FUN is to be applied.

FUN

A function to be applied to each element of X.

Silent

A logical value. If TRUE, the function suppresses the return value of FUN and returns NULL invisibly. If FALSE, the function returns the result of applying FUN over X.

...

Additional arguments to be passed to FUN.

Value

If Silent is TRUE, returns NULL invisibly, otherwise returns a list of the same length as X, where each element is the result of applying FUN to the corresponding element of X.

Examples

par(mfrow = c(1,2), oma = c(0.25, 0.25, 0.25, 0.25), mar = c(3,3,3,1))
lapply(list(x = 100:110, y = 110:120), function(V) {
    plot(V, las = 1, main = "lapply")
})

#> $x
#> NULL
#> 
#> $y
#> NULL
#>
