1 Introduction
The Sujatha distribution, introduced by Shanker (2016), is a one-parameter lifetime distribution that has been successfully applied to lifetime, reliability, biological and engineering data. The SujathaDist package provides computational tools for distributional analysis, random number generation, parameter estimation and goodness-of-fit assessment.

4 Distribution functions
Explain
Density Distribution Quantile Random generation
Example

dsujatha(1, theta)
psujatha(1, theta)
qsujatha(.5, theta)
rsujatha(10, theta)
5 Visualization
Include plots such as:
curve(dsujatha(x,2), from=0, to=10, lwd=2)
and
curve(psujatha(x,2), from=0, to=10, lwd=2)
