a) Extract every nth element of a given vector Example: Vector consists of elements from 1 to 30 (5M) Let n=5 Output: 1611162126 b) Soil pH is a measure of the acidity or basicity of a soil. pH is defined as the negative logarithm of the activity of hydronium ions in a solution. In soils, it is measured in a slurry of soil mixed with water, and normally falls between 3 and 10 , with 7 being neutral. Write a R program to convert a given pH levels of soil to an ordered factor. (5M) Example: Let ph=[1,3,10,7,5,4,3,7,8,7,5,3,10,10,7] Output: 3107NA>37310107 Levels: 3
