Reading .txt file to tab in R - r

Question

I want to read .txt file in R which is exported by this lines:
cat(sprintf("%s\n",paste0(matematykData)),file=nazwapliku2,append = TRUE)
The line is in loop so it saves it line by line, and the variable matematykData is a 1dim tab that contains only one record which is replaced by another record on the next run of "for loop" and it looks like this:
[1] "1884"
The reading method i use in another R script is:
dane2=read.table(file=nazwapliku2,sep="\n",skipNul= FALSE)
From this i get a string without any rows and columns that looks like this:
2962 1847
2963 1866
2964 1906
2965 429
2966 450
2967 450
2968 1910
2969 1900
2970 1889
Where the first "column" is the number of line. I want to convert that string to tab so i can reffrence every row of it, simply by using dane2[i] where "i" is the number of row i'am looking for. I'm not sure if i should change the way it's beening saved or readed or should i just read it and then convert it.
I also have other variable that needs to be converted and its more complicated because it contains 3 records per row: full_name,date and place of birth,date and place of death. The method i use for saving it is the same:
cat(sprintf("%s\n%s\n%s\n",paste0(matematyk[1]),paste0(matematyk[2]),paste0(matematyk[3])),file=nazwapliku1,append = TRUE)

Answer 1

For the first case it should work with dane2[i] for the row number.
You have to distinguish between records and variables.
In the second case I understand it that you have several records, each with the 5 variables
full_name, date of birth, place of birth, date of death, place of death
In that case you need to change your way of saving your data. In between the variables you need to use for example \t to separate the variables, and only use \n as the last in your format string for sprintf() call to separate the individual records.
