If there are several matrix arguments, they must all have the same number of columns (or rows) and this will be the number of columns (or rows) of the result. For cbind (rbind), vectors of zero length (including NULL) are ignored unless the result would have zero rows (columns), for S compatibility. In the model, I am using cbind for both the dependent and independent variables. frame() if one of the arguments is a data. Combines any number of R objects into a single matrix, with each input corresponding to the greater of 1 or ncol.

The short answer is: you cannot (get rid of NAs in cbind()), because cbind() is meant to output a rectangular table (data. 1":Details. Add a. ). For cbind (rbind) the column (row) names are taken from the colnames (rownames) of the arguments if these are matrix-like. Rで作ったデータフレームに追加したいデータがあります。. cbind(df2, df1[,2, drop=FALSE]) When you only select one column from a data. Now I see that this is actually supposed to work. combine=cbind) %dopar% { tempMatrix = {} tempMatrix = functionThatDoesSomething () #calling a function cbind (finalMatrix, tempMatrix) } Running things in parallel requires quite a bit of overhead. roll join with start/end window 3. 12.
