Description

Function to create a simple barplot

Usage

general.bar_plot_simple(freq, labels = NULL, labels.ab = NULL, file.name,
  col = "tomato3", cex.lab = 1, cex.lab.ab = 1, cex.x = 1, xlab = "",
  ylab = "Frequency", add.legend = FALSE, leg.lab = NULL,
  leg.col = NULL, leg.title = NULL, mar = c(5, 4, 3, 1), png.width = 6,
  png.height = 5)

Arguments

freq	vector with the bar heights, e.g. a frequency table ('table()' output), names will be used for bar labels if 'labels' is not specified
labels	bar labels (default=NULL)
labels.ab	additional labels, which are placed above the bars (default=NULL)
file.name	name for the PNG output file (without '.png' ending)
col	color for the bars (default='tomato3'). if more than one color is specified,
cex.lab	size of the bar labels (default=1)
cex.lab.ab	size of the bar labels above the bars (default=1)
cex.x	size of the x-labels (default=1)
xlab	label for the x-axis (default=”)
ylab	label for the y-axis (default='Frequency')
add.legend	TRUE/FALSE should a legend be added underneath the plot only works if legend parameters are specified (default=TRUE)
leg.lab	labels for the legend (default=NULL)
leg.col	colors for the legend (default=NULL)
leg.title	title for the legend (default=NULL)
mar	plot margin (default=c(5,4,3,1))
png.width	width of the PNG-file in inches (default=6)
png.height	height of the PNG-file in inches (default=5)

Value

PNG file with the barplot ('file.name.png') and a numeric vector with size of the PNG-file in inches for rescaling in RTF

Examples

## Not run: 
set.seed(42)
x <- sample(1:30, size=500, replace=TRUE)
freq <- table(x)

general.bar_plot_simple(freq, labels.ab=1:30, file.name="test", 
                col=rep(c('tomato3','tomato3','skyblue2'), 10), 
                cex.lab=.7, cex.lab.ab=.8, cex.x=.9,
                ylab="Bar Height", 
                add.legend=TRUE, leg.title="Color",
                leg.lab=c('red','blue'), leg.col=c('tomato3','skyblue2'),
                mar=c(4,4,3,1))
