Replacement of certain percentage of element in vector in r -


please, want replace 25% of deleted element in vector below maximum of numbers+550*deleted element i.e x=rnorm(100,1,4) want delete 25% of elements in x want replace each of deleted element of x 'maximum of x + 550*deleted elements'

thanks

i not 100% on asking after.

n = 100 # size of x x = rnorm(n,1,4)

get positions of 25% of elements in x randomly

rep = sample(x = 1:n, size = 0.25*n, replace = false)

update elements in x selected replacement

x[rep] = max(x) + 550*x[rep]
