picSurv | R Documentation |
Produces figures of value for assessing survival fit given data.
picSurv(dataf, survObj, ncuts = 20, makeTitle = "Survival", ...)
dataf |
a dataframe with columns ‘size’ and ‘sizeNext’(‘size’ is continuous stage variable at t, ‘sizeNext’ is continuous stage at t+1); facultatively, dataf may include ‘covariate’ and ‘covariateNext’ for a single discrete covariate, indicating values at t, and at t+1, respectively; these must take values of sequential integers, starting at ‘1’. For models fitting growth increment, 'incr' or 'logincr' may be directly provided as a column in the dataframe, otherwise they are calculated as dataf$sizeNext-dataf$size or log(dataf$sizeNext-dataf$size), respectively. |
survObj |
an object of class survObj. |
ncuts |
number of consecutive values for which means of survival and continuous (e.g. size) stage are taken for the plotting. |
makeTitle |
character that defines title, defaults to "Survival" |
... |
extra arguments to plot (e.g, ylim, etc). |
Returns nothing.
