question: how to select a column from a dataframe in a function
Hi,
I am creating a function and ran into the problem of selecting a column
from a dataset. It seems as though the $ function (as in data$columnname)
does not apply in the function. In simplified version:
This works:
testf2<-function(data,columnnumber){print(data[,columnnumber])}
But this doesn't:
testf<-function(data,column){print(data$column)}
Even though the first solution works, I would like to be able to insert the
columnname in the function, instead of the columnnumber. How do I do that?
Thank you i...

help with function
...ontext_score column of deMirPresGenes. This is easy peasy!
Where I'm falling down is that if I run this function it complains that 'geneMetric' can't be found. Hmm - I've run it all line by line (i.e. not as a function) and it works but wrapped up like this it fails!
e.g.
>testF2 <- cumulMetric(testF1, deMirs$up)
Error in eval(expr, envir, enclos) : object 'geneMetric' not found
deMirs$up looks like this:
Probe? ? FC
hsa-miR-183? ? 2.63
hsa-miR-1275? ? 2.74
hsa-miR-495? ? 3.13
hsa-miR-886-3p? ? 3.73
hsa-miR-886-5p? ? 3.97
hsa-miR-144*? ? 6.62
hsa-miR-451? ? 7.9...
