I'm working on RStudio

a) I have to remove all properties that are not Einblishs, bareign, Parhs,Rahs. There fore remove samykkt b, like I have marked with red. Use droplevels()

b)Show how many assets (teg_eign) of each type(einblishs, bareign, parhs, rahs) translated:(single-family house, apartment, semi-detached, townhouse) are in areas (matssvaedi )(270, 300, 700).

Please write your code .

Do not answer it if you do not know it!
