pyramid (version 1.5)

pyramidf: Drawing population pyramid using data.frame within the specified frame

Description

Drawing population pyramid using data.frame. Detailed explanation is given in Japanese at http://minato.sip21c.org/swtips/R.html#PYRAMID.

Usage

pyramidf(data, Laxis=NULL, Raxis=NULL, 
 frame=c(-1.15, 1.15, -0.05, 1.1), 
 AxisFM="g", AxisBM="", AxisBI=3, Cgap=0.3, Cstep=1, Csize=1, 
 Llab="Males", Rlab="Females", Clab="Ages", GL=TRUE, Cadj=-0.03, 
 Lcol="Cyan", Rcol="Pink", Ldens=-1, Rdens=-1, main="", ...)

Arguments

data

A data.frame including left pyramid numbers in the 1st column and and right pyramid numbers in the 2nd column, where the numbers of males in each age-class are usually given to left numbers and those of females are to right numbers. If the data.frame includes 3rd column, it is used as age-class labels, otherwise the row.names(data) is used as age-class labels.

Laxis

A vector of axis for left pyramid. If missing, automatically given using pretty().

Raxis

A vector of axis for right pyramid. If missing, Laxis is used.

frame

A vector of frame c(x-left, x-right, y-bottom, y-top), to draw pyramid. Default frame is same as

AxisFM

A format code of formatC for plotting axis. If missing, "g" is used.

AxisBM

A big.mark of formatC for plotting axis. If missing, none.

AxisBI

A big.interval number of formatC for plotting axis. Default is 3

Cgap

The width of center gap (as ratio to each panel) to draw age-class. Default is 0.3

Cstep

The interval to write the labels of age classes. Default is 1

Csize

The font size factor to write the labels of age classes. Default is 1

Cadj

The vertical adjustment factor for the labels of age classes. Default is -0.03

Llab

The label of the left pyramid. Default is "Males".

Rlab

The label of the right pyramid. Default is "Females".

Clab

The label of the center age-class. Default is "Ages".

GL

Logical value to draw the vertical dotted lines. Default is TRUE.

Lcol

The color of the left pyramid. Default is "Cyan".

Ldens

The density of hatching lines (/inch) for left pyramid. Default is -1, when the pyramid will be filled.

Rcol

The color of the right pyramid. Default is "Pink".

Rdens

The density of hatching lines (/inch) for right pyramid. Default is -1, when the pyramid will be filled.

main

The main title of the pyramid.
