What is meant by words that R provides environment for statistical computing? -

r described as:

r language , environment statistical computing , graphics.

why r not called language statistical computing environment statistical computing?

i humbly understand emphasis on environment.

r called language , environment statistical computing because, unsurprisingly, both.

the environment refers fact r programme can perform statistical operations, spss (although has gui), sas, or stata. can perform anova, linear regression, t-tests, or other statistical method need.

the language refers fact r functional , object-oriented programming language, in effect usable inside environment. create object, while can create new functions perform new tasks.

so overall package includes statistical environment r programming language, commonly referred 'r' overall.

from what r?:

the term “environment” intended characterize planned , coherent system, rather incremental accretion of specific , inflexible tools, case other data analysis software.

incidentally, @christoph right there environments within r (like global environment, or environments local functions), don't think term refers to.
