How to test whether is.element() returns only TRUE's

I found one:

sum(is.element(c(1,4,2),c(1,2,3)))==length(c(1,4,2))

Are there others and perhaps more elegant ways?

Aihe: How to test whether is.element() returns only TRUE's

Hi,

How can I test, whether all the values that is.element() -function returns are TRUE's

Eg.

(is.element(c(1,4,2),c(1,2,3)))

[1]  TRUE FALSE  TRUE

This doesn't work:

(is.element(c(1,4,2),c(1,2,3)))==TRUE

[1]  TRUE FALSE  TRUE

Best,

With all().

all(is.element(c(1,4,2),c(1,2,3)))

[1] FALSE
