To
define a variable, the assignment symbol “ Example:
In the above equation following way we can define variable in R > a <-1 > b <-1 > c <--1 Following two way we can check any variable: > a [1] 1 > print(a) [1] 1 If we want to check all the define variable, then with the following command we can check it: > ls() [1] "a" "b" "c" Now we have defined the variable, in the following way we can get > x<-(-b + sqrt(b^2 - 4*a*c))/(2*a) > x [1] 0.618034 > x<-(-b - sqrt(b^2 - 4*a*c))/(2*a) > x [1] -1.618034 |
