Greetings -
I am working on some data that contain chemical names with air concentrations,
and I am creating a data frame with date/time and each chemical having its own
column. However, these are organic chemicals (e.g. 1-butene,
2,3,4-trimethylbenzene etc). The package I am going to be using the data with
is openair, and many of the great functions require you to specify a column
name which does not seem to work with improper column names- e.g.
smoothTrend(mydata, pollutant="1-Butene" and smoothTrend(mydata,
pollutant=mydata[,"1-Butene"])
I was wondering if there was a function to automatically convert these chemical
names (with all sorts of numbers and minuses in the beginning) to something
openair can handle? Or am I going to be stuck recoding several hundred
chemical names in my database?
