QRISK3 R package

Update

This respiratory has been updated to ver0.6 as CRAN version.

Introduction

This function allows you to calculate 10-year individual CVD risk using QRISK3-2017.

Additional terms

The following disclaimer must be held together with any risk score score generated by this code.  
If the score is displayed, then this disclaimer must be displayed or otherwise be made easily accessible, e.g. by a prominent link alongside it.
The initial version of this file, to be found at http://svn.clinrisk.co.uk/opensource/qrisk2, faithfully implements QRISK3-2017.
ClinRisk Ltd. have released this code under the GNU Lesser General Public License to enable others to implement the algorithm faithfully.
However, the nature of the GNU Lesser General Public License is such that we cannot prevent, for example, someone accidentally 
altering the coefficients, getting the inputs wrong, or just poor programming.
ClinRisk Ltd. stress, therefore, that it is the responsibility of the end user to check that the source that they receive produces the same 
results as the original code found at https://qrisk.org.
Inaccurate implementations of risk scores can lead to wrong patients being given the wrong treatment.
