Hi,
I request help with the following:
INPUT: A data frame where column "Lower" is a character containing numeric

mostly 2)

structure(list(State = c("Alabama", "Alaska", "Arizona", "Arkansas",
"California"), Lower = c("R 72?33",

Sum of Numeric Values in a DF Column
## Continuing with your data
AA <- stringr::str_extract_all(dd[[2]],"[[:digit:]]+")
BB <- lapply(AA, as.numeric)
## I think you are looking for one of the following two expressions
sum(unlist(BB))
sapply(BB, sum)

Relative Cumulative Frequency of Event Occurence
Hi,
My objective is to calculate "Relative (Cumulative) Frequency of Event
Occurrence" - something as follows:
Sample.Number 1st.Fly 2nd.Fly Did.E.occur? Relative.Cum.Frequency.of.E
1 G B No 0.000
2 B B Yes 0.500
3 B G No 0.333
4 G B No 0.250
5 G G Yes 0.400
6 G B No 0.333
7 B B Yes 0.429
8 G G Yes 0.500
9 G B No 0.444
10 B B Yes 0.500
Please refer to the code below:
