How to fix this error?
Fixing this error is based upon two different ideologies that are discussed below.
Ideology 1: When we want to deal with the 1-dimensional data structure.
When we are sure that we are going to deal with a 1-dimensional data structure (like a vector) then we can fix this error like the below example.
Example:
R
# R program to fix the error # Creating a vector vect = rep(1, 5) # Assign values in the created vector # Note that we have removed the comma (,) # Since we are dealing with 1-dimensional # data structure for(i in 1:5) { # Assigning 10 as the value # at the ith index of the vect vect[i] = 10 } |
Output:
Ideology 2: When we want to deal with the 2-dimensional data structure.
When we are sure that we are going to deal with a 2-dimensional data structure (like a matrix) then we can fix this error like the below example.
Example:
R
# R program to fix the error # Creating a 2-dimensional data structure (matrix) # mat has 5 rows and 5 columns mat = matrix(rep(0,5), nrow=5, ncol=5) # Assign values in the created matrix # Note that we have added the comma (,) # Since we are dealing with 2-dimensional # data structure for(i in 1:5) { # Assigning 10 as the value # at all columns of the ith row mat[i,] = 10 } # Print the matrix print(mat) |
Output:
How to Fix: incorrect number of subscripts on matrix in R
Getting errors in programming is quite common and their frequency increase when our source code becomes bulkier. In this article, we are going to discuss how to fix: the incorrect number of subscripts on the matrix in R.
This error doesn’t give us any clue at the first appearance. This error may occur due to a very small mistake. This error may be easy for programmers to make but finding this error sometimes becomes challenging for most of the programmers.
