conf_inter: Add confidence intervals to a plot

In cyrilmi/teaching: Contains some functions

Description

Add confidence intervals to a plot. Provide x and y vectors. Values can be Standard error (stder= TRUE,SE=SE) or upper condidence intervals and lower confidence itnervals (stder= FALSE).

Usage

conf_inter(x, y, se=SE, stder=TRUE, low_ci=lowci, up_ci=upci, z=0.1,col="black",lty=1, lwd=1)

Arguments

x	vectors of values on the x axis
y	vectors of values on the y axis, mean values
SE	vectors of values on the for the standard error or CI
stder	TRUE if you have SE values (1.96*SE), FALSE if you already have CI limits
low_ci	vector with lower confidence limits
up_ci	vector with upper confidence limits
z	how large should the end of the forizontal line of the confidence interval, default is 0.1
col	color, default is black
lwd	lwd line width, default is 1
lty	line type, default is 1

Examples

names    <- c("rodents","insectivores","hare",
"carnivores","carrion","insects","plants",
"birds","ungulates")
red_fox <- c(29,9.8,15,2.5,29.4,1.3,9.5,3.5,0)
