Hello, I have to deal with numbers with a decimal part as quarter, coming from two systems with different way to show decimals. I need to tell R these are in fact the same number. On one side my number are formatted this way : 2.2 , 2.4 and 2.6. On the other side, I have 2.25, 2.50 and 2.75. All numbers are in fact 2.1/4, 2.1/2, 2.3/4. How can I tell R 2.2 is 2.25, 2.4 is 2.50 and 2.6 is 2.75 ? TY for any help. Arnaud Gaboury A2CT2 Ltd.
