Sum of the number of occurrences R array

[Yarnabrina]

I'm not sure I understand what you're asking.

I'm guessing that you meant that you have the strings in a comma separated text file. Is that it?

If so, then it can be done easily. First, suppose there's a text file named segment.txt in the working directory. It's contents are in this form:

"Segments"
"TATLQAKA"
"QCLKMLET"
"EARKIFRF"
"SKKELKEL"
"CPVGFLGN"
"VNTQPGFH"
"GDGRGDIC"
"IPSNFVSP"
"EFFRGLNI"
"SCTYQLAR"

Then, read that file in R using read.csv and use the rest of the code.

By the way, I found that strsplit can be used in this instead of stringr::str_split_fixed. Hence, being biased, let me post that solution too (essentially they are same).

library(package = "dplyr")

dataset <- read.csv(file = "segment.txt",
                    stringsAsFactors = FALSE)

do.call(what = rbind,
        args = strsplit(x = dataset$Segments,
                        split = "")) %>%
  as.data.frame() %>%
  mutate_all(.funs = ~ table(.)[.]) %>%
  mutate(strings = dataset$Segments,
         scores = rowSums(.[-9]))

Now, if your question is answered, will you please consider marking this thread as solved?

If you don't know how to do it, please take a look at this thread:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …
