Witryna13 kwi 2016 · The is.finite works on vector and not on data.frame object. So, we can loop through the data.frame using lapply and get only the 'finite' values.. lapply(df, function(x) x[is.finite(x)]) If the number of Inf, -Inf values are different for each column, the above code will have a list with elements having unequal length.So, it may be better to leave … Witryna4 lut 2016 · So I want to be able to append NA's to log_returns so I can put them in a data.frame.

Witryna8 sty 2016 · Your code is not entirely reproducible (there's no running of the actual randomForest algorithm) but you are not replacing Inf values with the means of column vectors. This is because the na.rm = TRUE argument in the call to mean() within your impute.mean function does exactly what it says -- removes NA values (and not Inf …

WitrynaFaulty input. Reason: you have an input with nan in it! What you should expect: once the learning process "hits" this faulty input - output becomes nan. Looking at the runtime log you probably won't notice anything unusual: loss is decreasing gradually, and all of a sudden a nan appears. Witryna7 sie 2013 · Another way you could possibly get NaN from mean (vector) without having any such values in your data is if both Inf and -Inf appear there. I.e., mean ( [-Inf 1 2 3 Inf]) returns NaN. To check for this, you can do the following: any (vector==Inf) && any (vector==-Inf) Then you can do.
