need to run base R first
<code>manipulate(plot(1:x), x = slider(5, 10))</code>

Create a blended curve from two survival curves, which is particularly useful
for survival extrapolation in health technology assessment. The main idea is to
mix a flexible model that fits the observed data well with a parametric model that
encodes assumptions about long-term survival. The two curves are blended into a
single survival curve that is identical to the first model over the range of
observed times and gradually approaches the parametric model over the extrapolation
period based on a given weight function. This approach allows for the inclusion of
external information, such as data from registries or expert opinion, to guide
long-term extrapolations, especially when dealing with immature trial data.
