MATRIX OPERATIONS (Manipulations, Combining, Length, etc.) IN R-PROGRAMMING|| DATA STRUCTURES IN R

Operations on Matrix

1. Add rows & cols

Rows - rbind(matrix_name,data)
Cols - cbind(matrix_name,data)

2. Deleting rows & cols

Single element - matrix[-c(index)]
Entire Row - matrix[-c(row_num),]
Entire Col - matrix[,-c(col_num)]
Multiple rows & cols - matrix[-c(row_num),-c(col_num)]

3. Searching an element

in - membership operator
element %in% matrix_name

4. Dimension of matrix

dim(matrix_name) - it will display rows followed by columns

5. Length of matrix

length(matrix_name) - it will display total number of elements in matrix.

6. Finding number of rows & number of columns

nrow(matrix_name) - return number of rows
ncol(matrix_name) - return number of cols

7. Loop the matrix elements

for(row in 1:nrow(m))
{
for(col in 1:ncol(m))
{
matrix[row,col]
}
}

8. Combining two matrices

m1
m2
res=rbind(m1,m2)
res=cbind(m1,m2)
