What does the quantile function in the R language do?

In the R language, the quantile function is used to calculate the percentiles of a vector or matrix. Percentiles are values that divide a set of data into equal parts, for example, dividing the data into four equal parts gives the quartiles. The quantile function can calculate any percentile or quartile, including the median (50th percentile) and quartiles (25th and 75th percentiles). The syntax of the function is as follows:

Compute quantiles for a given values of x at specified probabilities using type 7 method.

Description of Parameters:

1. x: Input vector or matrix.
2. probs: This is used to specify the probability values for the quantiles to be calculated, which can either be a number or vector between 0 and 1.
3. na.rm: Specifies whether to ignore missing values, with a default setting of FALSE.
4. names: Should the returned results be named, default is TRUE.
5. This parameter is used to specify the method for calculating percentiles, with a default value of 7 representing the 7th method out of a total of 9 options.

The function returns a vector containing the quantiles at the specified probability values.
