lplot {Rlab}

Label plot

Description

Plots x versus y with optional labels. The x or y variable may be a character vector, but not both.

Usage

lplot(x, y, labels = "*", srt = 0, tcex = 0.7, ...)

Arguments

x

Vector to be graphed on x-axis. May be a character vector, if y is numeric.

y

Vector to be graphed on y-axis. May be a character vector, if x is numeric.

labels

Character vector containing the labels for individual points.

srt

A numerical value specifying (in degrees) how strings should be rotated. It is unwise to expect values other than multiples of 90 to work. See help on par for more information.

tcex

A numerical value giving the amount by which the labels text or symbols should be scaled relative to the default.

...

Other arguments controlling the plot. Many graphical plotting arguments may be used. See help on plot or par for more information.

Examples

# Create some Normal data
set.seed(123)
temp<- data.frame(matrix(rnorm(12*8), ncol=12))
pos<- c(1:6,9:14)
lplot(temp)

# Now see some labels
lplot(temp, labels=paste("Y",1:12), tcex=.5)


# Create a data set with two factors (age and gender)
race<-data.frame(c(1.02,.99,1.11,1.30,1.09,1.26,1.21,1.19,1.30,1.45,1.34,1.49),
                 c('M','M','M','M','M','M','F','F','F','F','F','F'),
                 c('under 50','under 50','under 50','over 50','over 50','over 50',
                   'under 50','under 50','under 50','over 50','over 50','over 50'))
names(race)<-c("time","gender","age")

# Plot the data to see the factors
lplot(race$gender, race$time, race$age)
