Hi,
While executing rfImpute() in order to impute missing values in the data set I
receive below error :
| Out-of-bag |
Tree | MSE %Var(y) |
800 | 2.979e+04 1.02 |
Error in prox[miss, -miss, drop = FALSE] %*% xf[, j][-miss] :
requires numeric/complex matrix/vector arguments
Has anyone experienced it aware of the cause? Below is the command I used to :
x_tr_imp <- rfImpute(x_train[,-c(1,7)], x_train$Outlet_Sales, iter=5, 800)
Regards,
Sandeep S. Rana

5800 **not 5, 800** , no commas and no spaces. Please read an R tutorial or two to learn how to properly work with R if this is not merely a typo. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Sun, Feb 7, 2016 at 7:19 AM, Sandeep Rana <sunnysingha.analytics at gmail.com> wrote:> Hi, > While executing rfImpute() in order to impute missing values in the data set I receive below error : > > | Out-of-bag | > Tree | MSE %Var(y) | > 800 | 2.979e+04 1.02 | > Error in prox[miss, -miss, drop = FALSE] %*% xf[, j][-miss] : > requires numeric/complex matrix/vector arguments > > Has anyone experienced it aware of the cause?

Oh! It was a typo. ntree=800 was to be specified. Thanks Bret.> .On 07-Feb-2016, at 8:58 PM, Bert Gunter <bgunter.4567 at gmail.com> wrote: > > 5800 **not 5, 800** , no commas and no spaces. > > Please read an R tutorial or two to learn how to properly work with R > if this is not merely a typo. > > -- Bert > Bert Gunter > > "The trouble with having an open mind is that people keep coming along > and sticking things into it." > -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) > > > On Sun, Feb 7, 2016 at 7:19 AM, Sandeep Rana > <sunnysingha.analytics at gmail.com> wrote: >> Hi, >> While executing rfImpute() in order to impute missing values in the data set I receive below error : >> >> | Out-of-bag | >> Tree | MSE %Var(y) | >> 800 | 2.979e+04 1.02 | >> Error in prox[miss, -miss, drop = FALSE] %*% xf[, j][-miss] : >> requires numeric/complex matrix/vector arguments >> >> Has anyone experienced it aware of the cause?
