read.table - In R, how to read file with custom end of line (eol) -

-

i have text file read in r (and store in data.frame). file organized in several rows , columns. both "sep" , "eol" customized.

problem: custom eol, i.e. "\t&nd" (without quotations), can't set in read.table(...) (or read.csv(...), read.csv2(...),...) nor in fread(...), , can't able find solution.

i'have search here ("[r] read eol" , other don't remember) , don't find solution: 1 preprocess file changing eol (not possible in case because fields can find \n, \r, \n\r, ", ... , reason customization).

thanks!

you approach 2 different ways:

a. if file not wide, can read desired rows using scan , split desired columns strsplit, combine data.frame. example:

# provide reproducible example of file ("raw.txt" here) starting your_text <- "a~b~c!1~2~meh!4~5~wow" write(your_text,"raw.txt"); rm(your_text)    eol_str = "!" # whatever character(s) rows divide on sep_str = "~" # whatever character(s) columns divide on  # read , parse text file    # scan gives array of row strings (one string per row) # sapply strsplit gives list of row arrays (as many elements per row columns) f <- file("raw.txt") row_list <- sapply(scan("raw.txt", what=character(), sep=eol_str),                     strsplit, split=sep_str)  close(f)  df <- data.frame(do.call(rbind,row_list[2:length(row_list)])) row.names(df) <- null names(df) <- row_list[[1]]  df #   b   c # 1 1 2 meh # 2 4 5 wow

b. if doesn't work, agree @bondeddust need external utility -- can invoke in r system() , find/replace reformat file read.table. invocation specific os. example: https://askubuntu.com/questions/20414/find-and-replace-text-within-a-file-using-commands . since note have \n, , \r\n in text already, recommend first find , replace them temporary placeholders -- perhaps quoted versions of -- , can convert them after have built data.frame.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
