R: Representation of an object in a graph by a picture

s.logo {ade4} | R Documentation

## Representation of an object in a graph by a picture

### Description

performs the scatter diagrams using pictures to represent the points

### Usage

    s.logo(dfxy, listlogo, klogo=NULL, clogo=1, rectlogo=TRUE,
        xax = 1, yax = 2, neig = NULL, cneig = 1, xlim = NULL, ylim = NULL,
        grid = TRUE, addaxes = TRUE, cgrid = 1, include.origin = TRUE,
        origin = c(0, 0), sub = "", csub = 1.25, possub = "bottomleft",
        pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE)

### Arguments

`dfxy` | a data frame with at least two coordinates
`listlogo` | a list of pixmap pictures
`klogo` | a numeric vector giving the order in which pictures of listlogo are used; if NULL, the order is the same than the rows of dfxy
`clogo` | a numeric vector giving the size factor applied to each picture
`rectlogo` | a logical to decide whether a rectangle should be drawn around the picture (TRUE) or not (FALSE)
`xax` | the column number for the x-axis
`yax` | the column number for the y-axis
`neig` | a neighbouring graph
`cneig` | a size for the neighbouring graph lines used with par("lwd")*`cneig`
`xlim` | the ranges to be encompassed by the x axis, if NULL, they are computed
`ylim` | the ranges to be encompassed by the y axis, if NULL, they are computed
`grid` | a logical value indicating whether a grid in the background of the plot should be drawn
`addaxes` | a logical value indicating whether the axes should be plotted
`cgrid` | a character size, parameter used with par("cex")* `cgrid` to indicate the mesh of the grid
`include.origin` | a logical value indicating whether the point "origin" should be belonged to the graph space
`origin` | the fixed point in the graph space, for example c(0,0) the origin axes
`sub` | a string of characters to be inserted as legend
`csub` | a character size for the legend, used with `par("cex")*csub`
`possub` | a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")
`pixmap` | an object 'pixmap' displayed in the map background
`contour` | a data frame with 4 columns to plot the contour of the map : each row gives a segment (x1,y1,x2,y2)
`area` | a data frame of class 'area' to plot a set of surface units in contour
`add.plot` | if TRUE uses the current graphics window

### Value

The matched call.

      	rect(min(a1$x), min(a1$y), max(a1$x), max(a1$y), col = "lightblue")
      	invisible(lapply(split(a1, a1$id), function(x) polygon(x[, -1],col = "white")))

      	listico <- ggtortoises$ico[as.character(ggtortoises$pop$carap)]

      } else {
      	data(capitales, package = "ade4")
      	# 'capitales' data doesn't work with ade4 anymore
        g3 <- s.logo(capitales$xy[sort(rownames(capitales$xy)), ], capitales$logo,
          Sp = capitales$Spatial, pbackground.col = "lightblue", pSp.col = "white",
          pgrid.draw = FALSE)
      }
