Hi all,
I had a fish telemetry data with more then 11 million lines. I had some
false records in the data, that I have to eliminate. I can solve this using
a loop, but I think that dplyr:: filter could be faster and elegant. I just
can't figure out how to do it.
At this moment, I already summariz

Hello R-Helpers!
I have a vector of times of events that time is fraction of 1, because
it was calculated in excel. Are there some way to format a period
greater than 24h in a format like excel [h]:mm:ss?
Exemple:
test = c(1.424708, 0.028674)
> chron (times. = test [2], format = "h:m:S")
[1] 00

Hello R-Helpers!
I have a data-frame as below (dput in the end of mail) and need to
select just the first sequence of occurrence of each "Group" in each
"ID".
For example, for ID "1" I have two sequential occurrences of T2 and
two sequential occurrences of T3:
> test [test$ID == 1, ]
ID Group
13 matches
