Utility function
Plot line with confidence intervals.
plot_error( x, fit, se.fit, se.fit2 = NULL, shade = FALSE, f = 1, col = "black", ci.lty = NULL, ci.lwd = NULL, border = FALSE, alpha = 0.25, ... )
x |
Vector with values on x-axis. |
fit |
Vector with values on y-axis. |
se.fit |
Vector with standard error; or when |
se.fit2 |
Optional: lower values confidence interval. |
shade |
Logical: whether or not to produce shaded regions as confidence bands. |
f |
Factor for converting standard error in confidence intervals. Defaults to 1. Use 1.96 for 95% CI, and 2.58 for 99% CI. |
col |
Color for lines and confindence bands. |
ci.lty |
Line type to be used for the error lines, see
|
ci.lwd |
Line type to be used for the error lines, see
|
border |
The color to draw the border for the shaded confidence interval. The default, FALSE, omits borders. |
alpha |
Transparency of shaded area. Number between 0 (completely transparent) and 1 (not transparent). |
... |
Optional arguments for the lines and shaded area. |
