error_bar: gsplot error bars

In USGS-R/gsplot: Geological Survey Plotting

gsplot error bars

Description

Creates vertical and horizontal error bars around plot points.

Usage

error_bar(object, ...)

Arguments

object	gsplot object
...	Further graphical parameters may also be supplied as arguments. See 'Details'.

Details

Additional graphical parameter inputs:

• x, y location of error_bar origin

• offset.up, offset.down the y-value specifying the error above the point (high) and below the point (low)

• offset.right, offset.left the x-value specifying the error above the point (high) and below the point (low)

• epsilon width of the end of the error bar (in inches)

• legend.name name that appears in the legend, see legend for more legend parameters

Examples

gs <- gsplot()
gsNew <- points(gs, y=c(3,1,2), x=1:3, xlim=c(0,NA),ylim=c(0,NA),
            col="blue", pch=18, legend.name="Points")
gsNew <- lines(gsNew, c(3,4,3), c(2,4,6), legend.name="Lines")
gsNew <- abline(gsNew, b=1, a=0, legend.name="1:1")
gsNew <- legend(gsNew, location = "topleft",title="Awesome!")
gsNew <- grid(gsNew)
gsNew <- error_bar(gsNew, 1:3, y=c(3,1,2), 
                   offset.up=c(0.5,0.25,1), offset.down=0.1)
gsNew <- error_bar(gsNew, x=1:3, y=c(3,1,2), 
                   offset.left=c(.2,NA,.2), 
                   offset.right=.2, col="red",lwd=3)
gsNew <- title(gsNew, "Graphing Fun")

yData <- rnorm(100,mean=10000, sd=1000) 
gs <- gsplot() %>%
   points(1:100, yData, log="y") %>%
   error_bar(50:60, yData[50:60], offset.up=250)
