## R Calculate Standard Error

## Barplot With Error Bars R

## The following lines up correctly: ggplot(my_data, aes(x=day, weight=mid, ymin=mid-sigma, ymax=mid+sigma, fill=group)) + geom_bar (position=position_dodge(), aes(y=mid), stat="identity") + geom_errorbar (position=position_dodge(width=0.9), colour="black") + geom_point (position=position_dodge(width=0.9), aes(y=mid, colour=group)) share|improve this answer answered Oct 24

See ?geom_bar for examples. (Deprecated; last used in version 0.9.2) p p + geom_pointrange(limits) p + geom_crossbar(limits, width=0.2) # If we want to draw lines, we need to manually set the This can include aesthetics whose values you want to set, not map. Notice, that geom_errorbar and geom_point dodge in tandem. Built by staticdocs. http://glitchtest.org/error-bars/ggplot2-error-bars-example.html

How do we prove that something is unprovable? For each group's data frame, return a vector with # N, mean, and sd datac <- ddply(data, I should have included a reproducible example... However, when there are within-subjects variables (repeated measures), plotting the standard error or regular confidence intervals may be misleading for making inferences about differences between conditions.

How can I create a sophisticated table like the one attached? How is the Riemann zeta function equal to 0 at -2, -4, et cetera? Cracking in progress What reason could change people's mentality to treat each other as members of one kind? Could a Universal Translator be used to decipher encryption?

There's got to be an easier way to do this, right? These are basic line and point **graph with error bars representing** either the standard error of the mean, or 95% confidence interval. # Standard error of the mean ggplot

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). Check This Out Here is a simple piece of code: days = data.frame(day=c(0,1,8,15)); groups = data.frame(group=c("A","B","C","D", "E"), means=seq(0,1,length=5)); my_data = merge(days, groups); my_data$mid = exp(my_data$means+rnorm(nrow(my_data), sd=0.25)); my_data$sigma = 0.1; png(file="bar_and_errors_example.png", height=900, width=1200); plot(ggplot(my_data, aes(x=day,

Instead of columns of means, we just need to supply barplot() with a matrix of means.

Coding standard **for clarity: comment every** line of code? geom_errorbar inherits the dodge position from geom_bar so you can leave it unspecified, but geom_point does not so you must specify that value. I rolled a 20 on a stealth check. Error.bar Function R How safe are Wi-Fi Hotspots?

Please let me know by filling out this short online survey. I have a data frame like this concentration variable value sd 1 0 AF_B 0.3567126 0.010391001 2 0.5x AF_B 0.3355766 0.003480245 3 1x AF_B 0.3001138 0.009104821 4 5x AF_B 0.2658911 0.016312390 I see what you mean that unsetting linetype for the error bars should turn off the dodge positioning, so the undodged plot is quite sensible. http://glitchtest.org/error-bars/ggplot2-add-error-bars.html Any help appreciated.

Collaborator wch commented Mar 12, 2012 I'm pretty sure this isn't a bug -- the reason it stopped working for you is because a bug in 0.8.9 was fixed!

Only needs to be set at the layer level if you are overriding the plot defaults. Here we start by specifying the dodge (the spacing between bars) as well as the upper and lower limits of the x and y axes. This can be done in a number of ways, as described on this page. As I'm sure you are aware, this lets ggplot know where to look for y values.
