| fousy {GCDkit} | R Documentation | 
Using the function fousy can be added error bars for the x, and or, y
coordinate(s) of a binary plot.
fousy(x,y,sy,sx=0,fousek=0.05,col="black",lwd=1,figaro=TRUE)
| x, y | data points coordinates | 
| sx, sy | one sigma errors | 
| fousek | (optional) length of the error bars as a fraction of the FOV | 
| col | colour | 
| lwd | line width | 
| figaro | logical; should the error bars also added to the Figaro template? | 
This function plots error bars plus/minus 1 sigma. Optionally, these error bars are also added to the 
Figaro template of the current plot. In this case, the coordinates would be typically x.data
and y.data.
