I have a column of data of character class with 17700 values which looks like this:
410.9 564 784.7 100070.0 724.5 ...
I want to convert this data into numbers, however, my code:
data1$ICDCode <- as.numeric(levels(data1$ICDCode))[data1$ICDCode]
turns all the values into NAs. I don't think this is because of the decimal point since not all my data values include it (but they all turn into NAs too). How can I convert my data into numeric class?
