Visualization of regional indicators with the checkerplot

  checkerplot(data, cols=5, rows=5, geom="line", errorbar=FALSE, title=NULL,
    title.size=20, label.size=11, xbreaks=NULL, xlabels=NULL, ybreaks=NULL,
    ylabels=NULL, ymin=NULL, ymax=NULL, img=NULL, aes_geom=NULL,
    margin_yaxis=0, margin_yaxis2=0,margin_xaxis=0, margin_xaxis2=0, opts=NULL, ...)

`data`	data frame
`cols`	number of columns in the grid
`rows`	number of rows in the grid
`geom`	defines the geom, the geometric object, of the plot ("line", "bar", "point" are possible at the moment)
`errorbar`	TRUE/FALSE plot additional errorbars (testing only)
`title`	title of the plot, displayed above the plot
`title.size`	font size of the plot title
`label.size`	font size of the labels
`xbreaks`	number of breaks for the x-axis, default it is calculated automatically
`xlabels`	labels of the breaks (optional)
`ybreaks`	number of breaks for the y-axis, default it is calculated automatically
`ylabels`	labels of the breaks (optional)
`ymin`	minimum value of y-axis displayed, if not provided it will be automatically calculated
`ymax`	maximum value of x-axis displayed, if not provided it will be automatically calculated
`img`	vector containing all names (must equal the label column in the dataframe data) of pictures (pnm files) displayed beside the label
`aes_geom`	ggplot2 object to define the aesthetics of the geom

`margin_yaxis`	allows to adjust the distance from the plot to the left border of the grid for all elements with an y-axis and its annotation, because the difference number formats on the y-axis might lead to a little displaced plot area
`margin_yaxis2`	allows to adjust the distance from the plot to the left border of the grid for all elements with an y-axis but without annotation
`margin_xaxis`	allows to adjust the distance from the plot to the left border of the grid for all elements with an x-axis and annotation, because the difference number formats on the y-axis might lead to a little displaced plot area
`margin_xaxis2`	allows to adjust the distance from the plot to the left border of the grid for all elements with an x-axis but without annotation
`opts`	ggplot2 object to change settings in the ggplot2 plots
`...`	further arguments passed through

### EXAMPLE for US data
  data(coordUS)
  ## rearrange states which are far away:
  coordUS[coordUS$state=="AK","x"] <- 0.4  ## rearrange Alaska
  coordUS[coordUS$state=="HI","x"] <- 0.5       ## rearrange Hawaii
  ## optimal arrangement of the states:
  order <- optimal_grid_allocation(coordUS[,1:2],13,6)
  order <- data.frame(names=coordUS$state,order=order)
  ## load US healthy insurance data
  data(USdata1)
  data(USdata2)
  nam <- names(USdata1)
  ## delete previous order (optional)
  USdata1 <- USdata1[,-which(names(USdata1)=="order")]
  ## combine data and ordering:
  USdata1 <- merge(USdata1,order,all.x=TRUE,all.y=FALSE)
#  USdata1[is.na(USdata1$order),"order"] <- 14
  USdata1 <- USdata1[,nam]
  ## define directory with flags (pnm's):
  dirflags_us=paste(dirflags,"USStates/",sep="")
  USdata2[,3] <- USdata2[,3]*100
  checkerplot(USdata2[,-2], cols=13, rows=6, geom="bar",
            title="US private health insurance (in percent of the population)",
            title.size=18, ylabels=c(30,60,90), ybreaks=c(30,60,90),
            img=dirflags_us, margin_yaxis=-0.05, margin_yaxis2=-0.2,
        margin_xaxis=-0.4, margin_xaxis2=0)
