Hi everyone,
This may be very simple but I couldn't figure it out. I have this function
rsm.lm<-function(data,xvar='xCmin',yvar='yCmin') {
#some calculation......
recast(df, xvar~yvar, id.var=1:2, measure.var=3)
#some other operations
}
df is a dataframe defined internally within the function with two id
variables (xCmin and yCmin) and a measure variable. recast doesn't work and
keep saying "Casting formula contains variables not found in molten data:
xvar, yvar......"
I tried
as.name(xvar)~as.name(yvar)
get(xvar)~get(yvar)
cat(xvar)~cat(yvar)
eval(cat(xvar))~eval(cat(yval))
But none of these works. It only works when I explicitly specify the
formula as
recast(df, xCmin~yCmin, id.var=1:2, measure.var=3)
Is there a workaround this issue? Thanks.
