## How do I change the title of a plot in R?

There are two possible ways to do that :

- Directly by specifying the titles to the plotting function (ex : plot() ). In this case titles are modified during the creation of plot.
- the title() function can also be used. It adds titles on an existing plot.

## How do I change the scale of a plot in R?

## How do you scale in R?

scale() function in R Langauge is a generic function which centers and scales the columns of a numeric matrix. The center parameter takes either numeric alike vector or logical value. If the numeric vector is provided, then each column of the matrix has the corresponding value from center subtracted from it.

xlim(x) is just a shortcut for scale_x_continuous(limits = x) so if you want to set both limits and expansion you need. scale_x_continuous(expand=c(0,0), limits = x) END QUOTE.

## How do you convert skewed data in R?

Some common heuristics transformations for non-normal data include:

- square-root for moderate skew: sqrt(x) for positively skewed data,
- log for greater skew: log10(x) for positively skewed data,
- inverse for severe skew: 1/x for positively skewed data.
- Linearity and heteroscedasticity:

## How do you transform data in R?

## How do I make data normal in R?

In R, there are 4 built-in functions to generate normal distribution:

- dnorm() dnorm(x, mean, sd)
- pnorm() pnorm(x, mean, sd)
- qnorm() qnorm(p, mean, sd)
- rnorm() rnorm(n, mean, sd)

## What do you do if your data is not normally distributed?

Many practitioners suggest that if your data are not normal, you should do a nonparametric version of the test, which does not assume normality. From my experience, I would say that if you have non-normal data, you may look at the nonparametric version of the test you are interested in running.

## Is data normally distributed R?

Checking normality for parametric tests in R The normal distribution peaks in the middle and is symmetrical about the mean. Data does not need to be perfectly normally distributed for the tests to be reliable.

## How do I plot a normal distribution in Excel?

Creating a Bell Curve in Excel

- In cell A1 enter 35.
- In the cell below it enter 36 and create a series from 35 to 95 (where 95 is Mean + 3* Standard Deviation).
- In the cell adjacent to 35, enter the formula: =NORM.DIST(A1,65,10,FALSE)
- Again use the fill handle to quickly copy and paste the formula for all the cells.
