Tidiers for data.frame objects
Description
Data frame tidiers are deprecated and will be removed from an upcoming release of broom.
Usage
## S3 method for class 'data.frame'
tidy(x, ..., na.rm = TRUE, trim = 0.1)
## S3 method for class 'data.frame'
augment(x, data, ...)
## S3 method for class 'data.frame'
glance(x, ...)
Arguments
x |
A data.frame |
... |
Additional arguments for other methods. |
na.rm |
a logical value indicating whether |
trim |
the fraction (0 to 0.5) of observations to be trimmed from
each end of |
data |
data, not used |
Details
These perform tidy summaries of data.frame objects. tidy produces
summary statistics about each column, while glance simply reports
the number of rows and columns. Note that augment.data.frame will
throw an error.
Value
tidy.data.frame produces a data frame with one
row per original column, containing summary statistics of each:
column |
name of original column |
n |
Number of valid (non-NA) values |
mean |
mean |
sd |
standard deviation |
median |
median |
trimmed |
trimmed mean, with trim defaulting to .1 |
mad |
median absolute deviation (from the median) |
min |
minimum value |
max |
maximum value |
range |
range |
skew |
skew |
kurtosis |
kurtosis |
se |
standard error |
glance returns a one-row data.frame with
nrow |
number of rows |
ncol |
number of columns |
complete.obs |
number of rows that have no missing values |
na.fraction |
fraction of values across all rows and columns that are missing |

kurtosis and related tests. R package version 0.14.
