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.
will this do it for you:
x - c(2.2, 2.4, 2.6, 3.2, 3.4, 3.6)
# get integer part
x.i - as.integer(x)
# get fractional part
x.f - (x * 10) %% 10
# new result
result - x.i + ifelse(x.f == 2
+ , .25
+ , ifelse(x.f == 4
+ , .5
+
