a) how to find length of vector

CODE:

vtr =c(2,4,5,6,7,1,10)

vl = length(vtr)

print("Vector length:")

print(vl)


b) to sort the vector in decreasing order

CODE:

vtr =c(2,4,5,6,7,1,10)

#sort in decreasing order
sort(vtr, decreasing=TRUE)


c) to replace the third index value with 9

CODE:

vtr =c(2,4,5,6,7,1,10)
r1<-replace(vtr,3,"9")
print(r1)

d) to add one more element at the end of vector.

CODE:

vtr =c(2,4,5,6,7,1,10)
addnew<-append(vtr,40)
print(addnew)

e) To print all elements except first element of a vector.

CODE:

vtr =c(2,4,5,6,7,1,10)
new<-vtr[-1]
print(new)
