Tidy Randomly Generated Lognormal Distribution Tibble
Source:R/random-tidy-lognormal.R
tidy_lognormal.RdThis function will generate n random points from a lognormal
distribution with a user provided, .meanlog, .sdlog, and number of
random simulations to be produced. The function returns a tibble with the
simulation number column the x column which corresponds to the n randomly
generated points, the d_, p_ and q_ data points as well.
The data is returned un-grouped.
The columns that are output are:
sim_numberThe current simulation number.xThe current value ofnfor the current simulation.yThe randomly generated data point.dxThexvalue from thestats::density()function.dyTheyvalue from thestats::density()function.pThe values from the resulting p_ function of the distribution family.qThe values from the resulting q_ function of the distribution family.
Arguments
- .n
The number of randomly generated points you want.
- .meanlog
Mean of the distribution on the log scale with default 0
- .sdlog
Standard deviation of the distribution on the log scale with default 1
- .num_sims
The number of randomly generated simulations you want.
- .return_tibble
A logical value indicating whether to return the result as a tibble. Default is TRUE.
Details
This function uses the underlying stats::rlnorm(), and its underlying
p, d, and q functions. For more information please see stats::rlnorm()
