Re: [R] failure with merge

It looks like a common problem when using do.call("order", dataFrame). If dataFrame has a column whose name matches an argument to order you will get this problem. The solution is to use do.call("order", unname(dataFrame)). E.g., > do.call("order", tuneAcc) Error in match.arg(method) : 'arg'

[R] failure with merge

I am merging two data frames: tuneAcc <- structure(list(select = c(FALSE, TRUE), method = structure(c(1L, 1L), .Label = "GCV.Cp", class = "factor"), RMSE = c(29.2102056093962, 28.9743318817886), Rsquared = c(0.0322612161559773, 0.0281713457306074), RMSESD = c(0.981573768028697,
