For writing an R program that combines two given vectors by columns, and rows, we are using two built-in functions rbind() and cbind().
Both of these have the following syntax,
cbind(…, deparse.level = 1)
rbind(…, deparse.level = 1)
Where
In this R program, we directly give the values to combine. We are using two vectors into the variables v1 and v2 and variable results for holding combined vectors. First, we are displaying the original vector and then we combine it column-wise using the function cbind(v1,v2), and next time we combined it row-wise using rbind(v1,v2). Finally display the result
STEP 1: Assign variables v1 and v2 with vectors
STEP 2: Display the original vector values
STEP 3: combine vectors column-wise by calling cbind(v1,v2)
STEP 4: print the result vector
STEP 5: combine vectors row-wise by calling rbind(v1,v2)
STEP 6: print the result vector
v1 = c(4,5,6,7,8)
v2 = c(1,2,3,4,5)
print("Original vectors:")
print(v1)
print(v2)
print("Combines the vectors by columns:")
result = cbind(v1,v2)
print(result)
print("Combines the vectors by rows:")
result = rbind(v1,v2)
print(result)
