A good choice of the pch argument for such plots is 3 (plus sign) if you want to emphasize the interval more than the point estimate.

For bands (but not 'filled bands'), any number of other columns of y will be drawn as lines having the same thickness, color, and type as the main data line.

If it is a timeDate variable, two attributes are added to the resulting variable: scales.major and scales.minor. This is intended for timeDate variables.

Kind of like the loess function, but basically the mean +/- SEM at each time-point and the connection of the points being the mean. multiple lines). Copyright © 2016 R-bloggers. Word that **includes "food,** alcoholic drinks, and non-alcoholic drinks"?

## Error Bars In R

xscale allows one to use the default scales but specify only the x component of it for Dotplot method defaults to "bars" to draw error-bar type plots. http://r.789695.n4.nabble.com/error-bars-in-lattice-xyplot-with-groups-td801398.html Is it straight forward? Lattice Error Bars I was thinking that I would have to create a new panel which also included the tapply function. Geom_errorbar Most of the time I can save myself.

You only need to figure out the proper y axis scaling. > xyplot(y~x|f,data=xy,groups=dy,panel=function(x,y,groups,subscripts,...) {panel.xyplot(x,y,...)

Thanks in advance!

I've left the mean line in there to illustrate the difference between the two. Draws 2 sets (male, female) of 3 lines per panel. # xYplot(height ~ age | race, groups=sex, method='quantiles') # Examples of plotting raw data dfr <- expand.grid(month=1:12, continent=c('Europe','USA'), sex=c('female','male')) set.seed(1) dfr The data used represents intraoperative cardiovascular findings from patients undergoing surgery. http://johnlautner.net/error-bars/r-lattice-error-bars.html You will need to calculate it yourself and then draw it in you custom panel function.

How long does it take for trash to become a historical artifact (in the United States)? Is it possible? require(latticeExtra) xyplot(CI~Time, groups=Name, data=df, ty=c("l", "p"), + panel = function(x, y, ...) { + panel.xyplot(x, y, ...) + panel.linejoin(x, y, horizontal = FALSE,..., col="black", lty=1, lwd=4) + panel.smoother(x,y,se=TRUE, col.se="grey") + }

## In addition, tick marks separate the outer and inner segments.

By default, you will usually see a darker line segment for the low and high values, with the dotted reference line elsewhere. I computed a separate data.frame with all the values of interest, but wasn't able to "overlay" it on the xyplot. In either case, the name or label of the first argument is stored as an attribute "label" of the object returned by Cbind.
