If you want a quick function for the SE here's one: stderr<-function(x) sqrt(var(x,na.rm=TRUE)/length(na.omit(x))). You can also specify a general function of a data vector that returns a matrix of statistics for the method argument. Not the answer you're looking for? For numericScale x is any vector such as as.numeric(x) returns a numeric vector suitable for x- or y-coordinates.

Deepayan Sarkar has provided a very useful solution for simple circumstances (https://stat.ethz.ch/pipermail/r-help/2005-October/081571.html), yet I am having trouble getting it to work when the "groups" setting is enabled in xyplot (i.e. Join them; it only takes a minute: Sign up Add error bars seperately in lattice line-plot?

size can also specify a vector where the first character of each observation is used as the plotting symbol, if rangeCex is set to a single cex value.

These parameters are vectors or lists whose elements correspond to the added band lines (i.e., they ignore the central line, whose line characteristics are defined by lty, lwd, col). a timeDate variable x # xYplot(y ~ numericScale(x, label='Label for X') | country) # For this example could omit label= and specify # y ~ numericScale(x) | country, xlab='Label for X' xyplot(median ~ voice, groups=range, data=singer.ucl, ly = singer.ucl$lower, uy = singer.ucl$upper, Is there any way of doing this?

In either case, the name or label of the first argument is stored as an attribute "label" of the object returned by Cbind.

Lattice Error Bars This is used for example for bubble plots.

size values are linearly translated to this range, based on the observed range of size when x and y coordinates are not missing. To vary characteristics over the groups use e.g. minor.ticks a list with elements at and labels specifying positions and labels for minor tick marks to be used on the x-axis of each panel, if any.

I was thinking that I would have to create a new panel which also included the tapply function.

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. Thank you! xlab and ylab get default values from "label" attributes. You can also specify probs through methodArgs=list(probs=...).

A subscript method for Cbind objects subscripts the other matrix along with the main y vector. Specifying lwd.bands=1:4 will cause line widths of 1:4 to be used for every group, regardless of the value of lwd. The at element for scales.minor is used by panel.xYplot to add minor tick marks. this page more hot questions question feed lang-r about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation

If drawing bars and only one extra variable is given in ..., upper and lower values are computed as described above. By default, you will usually see a darker line segment for the low and high values, with the dotted reference line elsewhere. numericScale is a utility function that facilitates using xYplot to plot variables that are not considered to be numeric but which can readily be converted to numeric using as.numeric().

Arguments can be passed to that function via a list methodArgs. 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 To illustrate this, consider the singer data generated by the above linked solution previously submitted: ##################### library(lattice) singer.split <- with(singer, split(height, voice.part)) singer.ucl <- Do you just want to plot the SE for all points at a given measurement time point?

This is a vector when groups is present, and the order of the elements corresponds to the different groups, regardless of how many bands are drawn. But seeing, that the stderr function has a na.rm=T in it and the NAs only affect the computation of the SE and SD (but not the mean), I think it would nx defaults to the minimum of 40 and the number of points in the current stratum divided by 4. Usage panel.errbars(x,y,...,panel.xy=panel.xyplot, make.grid=c("horizontal","vertical","both","none"),ewidth=0) Arguments x,y numeric values, the points around which error bars are plotted.
