freq {rosetta}

Frequency tables

Description

Function to show frequencies in a manner similar to what SPSS' "FREQUENCIES" command does. Note that frequency is an alias for freq.

Usage

freq(
  vector,
  digits = 1,
  nsmall = 1,
  transposed = FALSE,
  round = 1,
  plot = FALSE,
  plotTheme = ggplot2::theme_bw()
)

## S3 method for class 'freq'
print(
  x,
  digits = x$input$digits,
  nsmall = x$input$nsmall,
  transposed = x$input$transposed,
  ...
)

## S3 method for class 'freq'
pander(x, ...)

frequencies(
  ...,
  digits = 1,
  nsmall = 1,
  transposed = FALSE,
  round = 1,
  plot = FALSE,
  plotTheme = ggplot2::theme_bw()
)

## S3 method for class 'frequencies'
print(x, ...)

## S3 method for class 'frequencies'
pander(x, prefix = "###", ...)

Arguments

vector

A vector of values to compute frequencies for.

digits

Minimum number of significant digits to show in result.

nsmall

Minimum number of digits after the decimal point to show in the result.

transposed

Whether to transpose the results when printing them (this can be useful for blind users).

round

Number of digits to round the results to (can be used in conjunction with digits to determine format of results).

plot

If true, a histogram is shown of the variable.

plotTheme

The ggplot2 theme to use.

x

The freq or frequencies object to print.

...

For frequencies, the variables of which to provide frequencies; for the print methods, additional arguments are passed on to the print function.

prefix

The prefix to use when printing frequencies, to easily prepend Markdown headers.

Value

An object with several elements, the most notable of which is:

dat

A dataframe with the frequencies

For frequencies, these objects are in a list of their own.

Examples

### Create factor vector
ourFactor <- factor(mtcars$gear, levels=c(3,4,5),
                    labels=c("three", "four", "five"));
### Add some missing values
factorWithMissings <- ourFactor;
factorWithMissings[10] <- factorWithMissings[20] <- NA;

### Show frequencies
freq(ourFactor);
freq(factorWithMissings);

### ... Or for all of them at one
frequencies(ourFactor, factorWithMissings);
