Hi Rosalinde,

If you set the argument err equal to "x", you'll get horizontal error bars.
Hope this helps,

Subject: [R] How to plot doubles series with different location using plotCI

Dear list

I would
like to create two series of plotted mean values and error bars, yet with different locations along the x-axis. 
Plotting of
first series using plotCI with the standard arguments goes without any problem.
However I do not succeed to add the second series in the same plot, which should be horizontally shifted from the first series along the x-axis. The “add=TRUE�
argument works well. Is there any argument defining the series location within plotCI. For example the tool “boxplot� contains the “at� argument. I found examples of plotCI where a vertical shift is realized (e.g.  “x=means+1e5�), never a horizontal shift. 

you find data information:


##mean and error first data series 

tmp <-
means <-
sapply(tmp, mean)
stdev <-
sapply(tmp, sd)
n <-
ciw <-
qt(0.975, n) * stdev / sqrt(n)

first data series
col="red", barcol="red", lwd=3, pch=18,
xaxt="n", yaxt="n",  ylab='benefit',xlab='typo', yaxs = 'i',ylim=c(0,8)) axis(side=1, at=1:3, labels=names(tmp), cex=0.7)  

##mean and error second data series 

tmp <-
means <-
sapply(tmp, mean)
stdev <-
sapply(tmp, sd)
n <-
ciw <-
qt(0.975, n) * stdev / sqrt(n)

problem: plotting second dataseries
uiw=stdev, col="steelblue", barcol="steelblue", lwd=2, pch=18, cex=2, xaxt="n", yaxt="n", ylab='qualite',xlab='type', yaxs = 'i',add=T)  ##this series of data is now superposed, but would like to put them horizontally shifted next to the red values

Thanks in

Rosalinde Van Couwenberghe
