It appears to have worked, although there were three little quirks.
The ; close(con); rm(con) didn't work for me; the first row of the
data.frame was all NAs, when all was said and done; and then there
were still three *** on the same line where the  was apparently
deleted.

This works for me:
# sample data
c <- character()
c[1] <- "2016-01-27 09:14:40 started a video chat"
c[2] <- "2016-01-27 09:15:20 https://lh3.googleusercontent.com/";
c[3] <- "2016-01-27 09:15:20 Hey "
c[4] <- "2016-01-27 09:15:22 ended a video chat"
c[5] <- "2016-01-27 21:07:11 started a v
Going back and thinking through what Boris and William were saying
(also Ivan), I tried this:
a <- readLines ("hangouts-conversation-6.csv.txt")
b <- "^([0-9-]{10} [0-9:]{8} )[*]{3} (\\w+ \\w+)"
c <- gsub(b, "\\1<\\2> ", a)
> head (c)
[1] "2016-01-27 09:14:40 *** Jane Doe started a video chat"

Can you build your data top-down?
schools <- paste("s", 1:6, sep="")
classes <- character()
for (school in schools) {
classes <- c(classes, paste(school, paste("c", 1:5, sep=""), sep = "."))
}
pupils <- character()
for (class in classes) {
pupils <- c(pupils, paste(class, paste("p", 1:10,
Many thanks Jeff and Linus,
Yes to Jeff,
OK with Linus but
classroom <- rep(c("C1","C2","C3","C4","C5","C6"), 50) [sample(1:300)]
how can I include the nested structure, I mean the teacher. Now, I would like
the 50 pupils belonging to C1 with T1, the 50 pupils belonging to C2 with T2,

Wouldn't the students/teachers/schools be enumerated and the properties you are
studying be random/correlated according to the enumerated values?

Dear R-Experts,
In a data simulation, I would like a balanced distribution with a nested
structure for classroom and teacher (not for school). I mean 50 pupils
belonging to C1, 50 other pupils belonging to C2, 50 other pupils belonging to
C3 and so on. Then I want the 50 pupils belonging to C1
Actually, you might go for 3.6.0-patched. There was a somewhat annoying bug
affecting the package installation menu in 3.6.0.
