Evaluate the cumulative distribution function of a LogNormal distribution


Evaluate the cumulative distribution function of a LogNormal distribution


## S3 method for class 'LogNormal'
cdf(d, x, drop = TRUE, elementwise = NULL, ...)



A LogNormal object created by a call to LogNormal().


A vector of elements whose cumulative probabilities you would like to determine given the distribution d.


logical. Should the result be simplified to a vector if possible?


logical. Should each distribution in d be evaluated at all elements of x (elementwise = FALSE, yielding a matrix)? Or, if d and x have the same length, should the evaluation be done element by element (elementwise = TRUE, yielding a vector)? The default of NULL means that elementwise = TRUE is used if the lengths match and otherwise elementwise = FALSE is used.


Arguments to be passed to plnorm. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.


In case of a single distribution object, either a numeric vector of length probs (if drop = TRUE, default) or a matrix with length(x) columns (if drop = FALSE). In case of a vectorized distribution object, a matrix with length(x) columns containing all possible combinations.
