Vudobar Limitations of R R is provided with a command line interface CLIwhich is the preferred user interface for power users because it e;icalc direct control on calculations and it is flexible. One can write their own code to build their own statistical tools. Why not ask them? R is highly extensible through the use of usersubmitted packages for specific functions or specific areas of study.

Tukinos [R] Epicalc package Go to the link: Thus whereas SAS and SPSS will give epidalc the details in the output from a regression or discriminant analysis, R will give the desired and minimal output and store the results in a fit object for subsequent interrogation by further R functions.
The other limitation is that, being an open source software, hackers can easily know about the weaknesses or loopholes of the software more easily than closed-source software and so it is more prone to bug attacks. One can write their own code to build their own statistical tools.
So many datasets remain unexplored, sometimes forever waiting to be analyzed even by simple exploratory and descriptive data analysis. Conclusions Being free of cost, it is surely a boon for researchers in developing countries and resource scarce institutions The quality of this software in terms of handling large datasets, having hundreds of functions with ever increasing number of add on packages and the neat outputs is also an advantage.
For basic biostatistical and epidemiological purposes Epicalc package is sufficient to start with and then to go on for other packages as and when required. Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.
One can use the nearest with respect to geographical location CRAN mirror to minimize network load. I understand, my point is merely that I think it would be considered both more polite and in general more accurate to inquire with the package maintainer first on matters like these. R is provided with a command line interface CLIwhich is the preferred user interface for power users because it allows direct control on calculations and it is flexible.
However, good knowledge of the language is required. The steep learning of R is a serious disadvantage which if eased by the introduction of menu driven R can make it more popular among the non-mathematicians dealing with epidemiological elicalc.
This article has been cited by other articles in PMC. The epiDisplay package information says:. The learning curve is typically longer than with a graphical user interface GUIepivalc it is recognized that the effort is profitable and leads to better practice finer understanding of the analysis; command easily saved and replayed.
Received Jan 24; Accepted Feb 3. R is an integrated suite of software facilities for data manipulation, calculation and epicalf display. But for developing countries, the scenario epiclac not change as expected because of the very high cost of the statistical packages. Footnotes Source of Support: R software introduction for stat Package for data exploration and result presentation.
Nil Conflict of Interest: With the introduction of softwares for statistical epicalf, things changed and data analysis came to be thought of something within the realm of possibility by the medical researchers. An introduction to R. It was first launched as a Disk Operating System DOS based version, which was command driven and difficult to learn by the medical researchers. The message says it was archived at the request of the maintainer. Analyzing epidemiological data has always been a matter of concern especially for those researchers who have a background of biological sciences and not of mathematics.
Frequently asked questions on R. On the other hand, epiclc has the potential to help young epidemiologists to learn the key terms and concepts based on numerical and graphical results of the analysis.
It requires some effort to find which package contains the statistical techniques that we require. As the dataset is usually epicalx in epidemiology, calculating even simple statistics like mean or standard deviation is quite cumbersome to be done epicqlc.
For many, even finding a statistician becomes difficult in their setting. It is important to use the normal precautions that is taken while downloading data on our epicqlc disk.
CLI is thus intimidating for beginners. On one hand, it assists data analysts in data exploration and management. I just thought someone would know and indeed Ben Bolker provided the answer. Formerly available versions can be obtained from the archive. CRAN does not have Windows systems and therefore cannot check for viruses.
