library(ggplot2)
library(pander)

Data report overview

The dataset examined has the following dimensions:

---

Feature Result

---

Number of observations 15

Number of variables 6

• Only variables that were deemed potentially problematic are included in this summary.

Checks performed

The following variable checks were performed, depending on the data type of each variable:

---

  character factor labelled numeric integer logical Date

---

Identify miscoded missing values $\times$ $\times$ $\times$ $\times$ $\times$ $\times$

Identify prefixed and suffixed whitespace $\times$ $\times$ $\times$

Identify levels with < 6 obs. $\times$ $\times$ $\times$

Identify case issues $\times$ $\times$ $\times$

Identify misclassified numeric or integer variables $\times$ $\times$ $\times$

Identify outliers $\times$ $\times$ $\times$

Please note that all numerical values in the following have been rounded to 2 decimals.

\fullline

region

• The following suspected missing value codes enter as regular values: \" \", \".\".

• The following values appear with prefixed or suffixed white space: \" \".

• Note that the following levels have at most five observations: \" \", \".\", \"OTHER\", \"a\", \"b\", \"c\", \"other\".

\fullline

id

• The variable is a key (distinct values for each observation).
