After this, we construct a ggplot object that contains information about the data frame we're using as well as the x and y variables. Most of the time I can save myself. Baking at a lower temperature **than the** recipe calls for Efficiently find whether a string contains a group of characters (like substring but ignoring order)? Misuse of parentheses for multiplication Why does a full moon seem uniformly bright from earth, shouldn't it be dimmer at the "border"?

## Error Bars In R

Instead of columns of means, we just need to supply barplot() with a matrix of means. Learn R R jobs Submit a new job (it's free) Browse latest jobs (also free) Contact us Welcome!

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.

The grid and lattice graphics systems also have specific functions for displaying error bars, e.g., the grid.arrow() function in the grid package, and the geom_errorbar(), geom_errorbarh(), geom_pointrange(), geom_linerange(), geom_crossbar() and geom_ribbon() Check This Out up vote 0 down vote favorite 2 I have a line-plot produced with lattice's xyplot.

After loading the library, everything follows similar steps to what we did above. here is what I have come up with so far: xyplot(mean.tort+t.ws~DateTime, pre, type=c("a", "p"), col=c("red", "blue"), main="Pre-Translocation", xlab=list(label="Date and Time", cex=1), ylab=list(label="Temperature (°C)", cex=1), scales = list(tck = c(1, 0), x=list(cex=0.8,

I tried to alter all 'lx' and 'ux' to 'ly' and 'uy' in panel.ci and prepanel.ci, but to no avail. share|improve this answer answered Nov 14 '13 at 18:17 sparrow 622415 Dear sparrow, thank you so much for this - you are my hero! =) I was playing around Here, we'll start by widening the plot margins just a tad so that nothing runs off the edge of the figure (using the par() function). Cylindersnand No.

Within these types of functions, some will accept the measures of dispersion (e.g., plotCI), some will calculate the dispersion measures from the raw values (bar.err, brkdn.plot), and some will do both Are there any historically significant examples?
