!x,mean,standard_dev,cumulative!!Returns the lognormal distribution of x, where ln(x) is normally distributed with parameters Mean and Standard_dev!is the value at which to evaluate the function, a positive number!is the mean of ln(x)!is the standard deviation of ln(x), a positive number!is a logical value: for the cumulative distribution function, use TRUE; for the probability density function, use FALSE!
