R Line Plot Standard Error


Defaults to blank for horizontal charts. Author(s) William Revelle See Also error.crosses for two way error bars, error.bars.by for error bars for different groups In addition, as pointed out by Jim Lemon on the R-help Join the conversation For example, '--ro' plots a dashed, red line with circle markers. http://vealcine.com/error-bars/r-plot-line-standard-error.php

Control the appearance of the marker using name-value pair arguments. The method below is from Morey (2008), which is a correction to Cousineau (2005), which in turn is meant to be a simpler method of that in Loftus and Masson (1994). Name is the argument name and Value is the corresponding value.

For horizontal error bars the following changes are necessary, assuming that the sdev vector now contains the errors in the x values and the y values are the ordinates: plot(x, y,

If you do not want to draw the lower part of the error bar at a particular data point, then specify the length as NaN. Ggplot2 Error Bars cap the width of the little lines at the tops and bottoms of the error bars in units of the width of the plot. It's a lot of code written for a relatively small return. par(mar = c(5, 6, 4, 5) + 0.1) plotTop <- max(myData$mean) + myData[myData$mean == max(myData$mean), 6] * 3 barCenters <- barplot(height = myData$mean, names.arg = myData$names, beside = true, las =

Plot Mean And Standard Deviation In R One way that we can construct these graphs is using R's default packages.

We'll use the myData data frame created at the start of the tutorial. 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.

Alternately, we can use Hadley Wickham's ggplot2 package to streamline everything a little bit. The default for ornt is 'vertical', which draws vertical error bars. Instead of columns of means, we just need to supply barplot() with a matrix of means. Control the lower and upper lengths of the vertical error bars using the yneg and ypos input argument options, respectively.
