Determines the location, i.e., index of the (first) minimum or maximum of a numeric vector. Usage which.min(x) which.max(x) x <- c( 1, 4, 3, 9, 6, 7) which.max(x) Output: \$Rscript main.r 4 # position {Or} Position particular number(another way) x Output: ...

x <- c(2 ,3 ,4 ,6,1) min(x) y <- c(78,34,5,67,41,33) max(y) Output: \$Rscript main.r 1 78

#### Find the maximum and minimum number in R Programming Language

x <- c(2 ,3 ,4 ,6,1) min(x) y <- c(78,34,5,67,41,33) max(y) Output: \$Rscript main.r 1 78

x <- c(2 ,3 ,4 ,4) y <-c(3, 4 ,5 ,6) print (x+y) print(x-y) print(x*y) print(x/y) print(x%%y) print(x^y) or sum(x,y) prod(x,y) Output: \$Rscript main.r 5 7 9 10 -1 -1 -1 -2 6 12 20 24 0.6666667 0.7500000 0.8000000 0.6666667...

#### Write a R Program to Two vector Variables (Addition, Subtraction, Multiplication, Division, Mod, Coefficient)

First R Program: print (“Hello world!”) Output: “Hello world!” print (“Hello World!”, quote-FALSE) Output: Hello World! print (paste (“Welcome”,”to”,”my”, “first”,”program”)) Output: “Welcome to my first program”

#### Simple way:” Hello world program in R”

First R Program: print (“Hello world!”) Output: “Hello world!” print (“Hello World!”, quote-FALSE) Output: Hello World! print (paste (“Welcome”,”to”,”my”, “first”,”program”)) Output: “Welcome to my first program”
