The `curve()`

function in `R`

is part of the ** graphic package**, which provides basic data visualization elements like box plots, bar plots, and so on.

** curve()** is used to draw a curve for the equation specified in the arguments.

```
curve(expr, to, from, col)
```

: This is the expression to be curved.`expr`

: This is the start of the range to be evaluated for the expression.`from`

: This is the end of the range to be evaluated for the expression.`to`

: This is to specify the color of the curve. This is an optional parameter.`col`

Note: Other graphical parameters like`xlable`

,`ylabel`

,`main`

, and so on, can also be passed as parameters.

f1 <- function(x) { sin(x) # Calculating Sine Value for the Plot. } curve(f1, -4, 4, col ="red") # Specifing the range between -4, 4.

Example code for the curve function

- Line 2: We define a function to calculate the sine value for the plot using
`sin(x)`

. We store this in`f1`

. - Line 5: We make the function call to
`curve`

. Here,`f1`

is passed as the expression, with a range from`-4`

to`4`

. The optional parameter`col`

is set to`"red"`

.
