Profile line (of multiple groups) in multiple items

Description

draws a profile line of means or medians in multiple items and groups

Usage

profileline(
  matrix,
  group = 1,
  type = "Median",
  groupnames = levels(factor(group)),
  main = "",
  col = 2:(length(unique(group)) + 1),
  pch = 1:length(levels(factor(group))),
  lty = 1:length(levels(factor(group))),
  lwd = 2,
  grid = TRUE,
  space_left = max(nchar(names(matrix)))/3 + 2.5,
  xlab = "",
  labels = "",
  extreme = FALSE,
  cex.axis.x = 1,
  cex.axis.y = 1,
  axis.top = TRUE,
  axis.bottom = TRUE,
  low_label = "",
  high_label = "",
  padj = 3,
  bottom.adj = 0,
  legend = TRUE,
  N_legend = TRUE,
  cex.legend = 1,
  title = TRUE
)

grid	draw grid
space_left	space to y axis of first bar
xlab	x axis label
labels	labels displayed on x axes (must be of length
extreme	only draw poles of labels (senseful for likert items)
cex.axis.x	cex of x axis
cex.axis.y	cex of y axis
axis.top	draw top axis
axis.bottom	draw bottom axis
low_label	lowest level

legend	draw legend
N_legend	draw legend of N observations per group
cex.legend	character expansation of legend
title	legends title

Examples

matrix<-data.frame(matrix(sample(-3:3,1000,T),ncol=20))
names(matrix)<-paste("Item",1:20); g<-paste("Group",rep(1:3,length=200))
for(i in 1:dim(matrix)[2]){matrix[,i]<-factor(matrix[,i],-3:3,c("fully disagree","2","3","4","5","6","fully agree"))}
profileline(matrix,g,main="",N_legend=T,pch="",type="Mean",ex=T,low="low",high="high",xlab="agreement")
