A formula giving the vectors containing the observed states and the corresponding observation times. For example,

y axis label. |
lwd |
Line width. See |
xlim |
x axis limits, e.g. c(0,10) for an axis ranging from 0 to 10. Default is the range of observation times. |

Mark the empirical survival curve at each censoring point,

Other arguments to be passed to the |
If the data represent observations of the process at arbitrary times, then
the first occurrence of the state in the data will usually be greater than
the actual first transition time to that state. Therefore the probabilities
plotted by plotprog.msm
will be overestimates.
