I am trying to read a CSV file that has barcodes in the first column, but when R gets it into a data.frame, it converts 1665535004661 to 1.67E+12.<
1665535004661
1.67E+12
You can use the numerals arguments when you are doing read.csv. So for example:
read.csv
read.csv(x, sep = ";", numerals = c("no.loss")) Where x is your data.
This preserves the value of the long integers and doesn't mess with their representation when you import the data.
