Plot Stratum Lengths
Description
The function makes a graphical representation of the stratum lengths.
Usage
## S3 method for class 'lengths'
plot(x, ..., log = FALSE, zeros.rm = TRUE)
Arguments
x |
an object of the class |
... |
other arguments to pass to the function |
log |
a logical value. If |
zeros.rm |
a logical value. If |
Details
The box-and-whisker plots give some information about the distribution of the stratum lengths for the observed categories along a given direction.
Value
An image is produced on the current graphics device; by the use of boxplot.lengths
, the same image is produced. The function returns a list with the following components:
stats |
a matrix containing the values used to plot the box-and-whisker plots. |
n |
a vector with the number of observations for each category. |
conf |
a matrix containing further values to draw the lower and upper extremes of the notch. |
out |
a vectors with the values of the outlier points. |
group |
a vector whose elements indicate to which category the outlier belongs. |
names |
a character vector with the names of each category. |

Examples
data(ACM)
direction <- c(0,0,1)
# Compute the appertaining directional line for each location
loc.id <- which_lines(ACM[, 1:3], direction)
# Estimate stratum lengths
gl <- getlen(ACM$MAT3, ACM[, 1:3], loc.id, direction)
# Plot the object gl
plot(gl)
