2. Disadvantage

R programming language is much slower than other programming languages such as MATLAB and Python. In comparison to other programming language, R packages are much slower. In R, algorithms are spread across different packages. The programmers who have no prior knowledge of packages may find it difficult to implement algorithms.

The main disadvantage of R is, it does not have support for dynamic or 3D graphics. The reason behind this is its origin. It shares its origin with a much older programming language “S.”

R is a very complicated language, and it has a steep learning curve. The people who don’t have prior knowledge or programming experience may find it difficult to learn R.

R lacks basic security. It is an essential part of most programming languages such as Python. Because of this, there are many restrictions with R as it cannot be embedded in a web-application.

In R, objects are stored in physical memory. It is in contrast with other programming languages like Python. R utilizes more memory as compared to Python. It requires the entire data in one single place which is in the memory. It is not an ideal option when we deal with Big Data.
