This function plots a probability density function of a sample proportion, shades the area under the curve, and computes the probability.
1 2 3 |
xshade |
A single number or vector of two numbers, denoting values on the x-axis where shading under the curve begins and ends. |
size |
Number of Bernoulli trials (one or more). |
prob |
Probability of Bernoulli success. |
lower.tail |
Logical; if |
xlab |
The label given to the sample proportion on the x-axis. |
xmin |
The minimum x-value to be graphed. |
xmax |
The maximum x-value to be graphed. |
xtic |
Logical or a vector of numbers.
If |
digits.prob |
The number of significant digits listed in the probability. |
digits.xtic |
The number of significant digits listed on the x-axis. |
main |
The main title given for the graph. |
col |
A vector of size two, specifying the colors of the density curve and the shading, respectively. |
lwd |
The line width illustrating the discrete probabilities. |
... |
Optional arguments to be passed to the |
When illustrating a left-sided p-value or any other left-sided probability,
xshade
should be a single number and set lower.tail=TRUE
(default).
When illustrating a right-sided p-value or any other right-sided probability,
xshade
should be a single number and set lower.tail=FALSE
.
When illustrating a two-sided p-value or any other two-sided probability,
xshade
should be a vector of two numbers and set lower.tail=TRUE
(default).
When illustrating the complement of a two-sided p-value or the complement of any other two-sided probability,
xshade
should be a vector of two numbers and set lower.tail=FALSE
.
