do.dotplot: Plot one or more variables in a dataframe as a dotplot.

In valentint/indstat: INDSTAT Utilities updated for 2021

Plot one or more variables in a dataframe as a dotplot.

Description

Plot one or more variables in a dataframe as a dotplot.

Usage

do.dotplot(x, ctvar = "NAME", var = "AAGR", grpvar, xlab, pch, col, legend, ...)

Arguments

x	data frame
ctvar	name of the variable containing the labels
var	Name of the variable to be presented as a dotplot
grpvar	Grouping variable
xlab	Label for the X-axis
pch	Characters to use for the dots
col	Colors
legend	Legend
...	Other parameters to be passed to lower level functions

Details

The input data is a data frame which contains as a minimum two variables: one variable of type factor which will be used for the labels - ctvar, and one numeric variable for the values - var.

Currently only one variable can be presented as a dotplot.

It is possible to have a grouping variable - then the dots can be presented by different color and symbol and a legend can be added.

Value

Returns an object of class "trellis". The update method can be used to subsequently update components of the object, and the print method (usually called by default) will plot it on an appropriate plotting device.

Examples

## Create a data frame: use ISIC Revision 3, 2-digits and a random variable
data(isic32)
head(isic32)
df <- isic32[-which(isic32$code=="D"),]     # remove "Total Manufacturing"
df$random <- runif(nrow(df), 1, 10)
do.dotplot(df, ctvar="description", var="random")

## Change X-label, color and dot symbol
do.dotplot(df, ctvar="description", var="random", xlab="Random Variable", col="red", pch=19)

## Add grouping variable - 3 categories
df$grp <- factor(round(runif(nrow(df), 1, 3)))
head(df)
legend.text <- c("Group1", "Group2", "Group3")
do.dotplot(df, ctvar="description", var="random", grpvar="grp", xlab="Random Variable", col=getcolors(3), pch=c(17,18,19), legend=legend.text)

## Get some real data - MVA for 100=Bulgaria for 2010
data(graphdata)
x <- get.50x51(yr=2010, ct=100)
x <- merge(x, isic32, by.x = "ISIC", by.y = "code")      ## Add ISIC descriptions
head(x)
do.dotplot(x, ctvar="description", var="VALUE", xlab="MVA (thousand USD at constant 2005 prices)")
