petsum: Print LaTeX event time summary
In reportRx: Tools for automatically generating reproducible clinical report

Wrapper for the etsum function that prints paragraphs of text in LaTeX

1 2	petsum(data, response, group = 1, times = c(12, 14), units = "months")

`data`	dataframe containing data
`response`	character vector with names of columns to use for response
`group`	string specifiying the column name of stratification variable
`times`	numeric vector of times you want survival time provbabilities for.
`units`	string indicating the unit of time. Use lower case and plural.

petsum(lung,c("time","status"))
petsum(lung,c("time","status"),"sex",c(1,2,3),"months")

 \textbf{1: } There are 138 patients. There were 112 (81\%) events. The median and range of the follow-up times is 224 (11-1022) months. The KM median event time is 326.1 with 95\% confidence Interval (22.9,270). The first and last event times occurred at 11 and 883 months respectively. The 12 and 14 month probabilities of 'survival' and their 95\% confidence intervals are 97 (94-100) and 96 (92-99) percent. 

 \textbf{2: } There are 90 patients. There were 53 (59\%) events. The median and range of the follow-up times is 292.5 (5-965) months. The KM median event time is 455.9 with 95\% confidence Interval (32.9,426). The first and last event times occurred at 5 and 765 months respectively. The 12 and 14 month probabilities of 'survival' and their 95\% confidence intervals are 99 (97-100) and 99 (97-100) percent.
