Convert timeslice to timeframes datatable r how to#

Īs shown in Table 5, we have constructed a matrix from a data.table by use of function as.matrix().Įxample 4: Transform Matrix to data.table Str(mat_2) # Display the structure of the data Mat_2 <- as.matrix(DT_2) # Convert a data.table to a matrix Str (DT_2 ) # Display the structure of the data # Classes ‘data.table’ and 'ame':Ĕ obs.

In this post, you can see how to select the numeric columns of a data.table or ame. If there is even one non-numeric column, all cells of the resulting matrix will be formed as characters. Note that for this conversion we only consider data.tables with purely numeric values. This example explains how to modify a data.table to a matrix. This example illustrates how to alter the structure of a ame to a data.table using the function as.data.table().Īs revealed in Table 4, we have managed to construct a data.table by executing the previous R programming syntax.Įxample 3: Transform data.table to Matrix You see that data frames and data tables have a very similar structure in R.Įxample 2: Transform ame to data.table

Str(DF_1) # Display the structure of the dataĪs shown in Table 3, we have created a ame with the previous R programming code.

of 3 variables: # $ v1: int 1 2 3 4 # $ v2: chr 'a' 'b' 'c' 'd' # $ v3: logi TRUE FALSE FALSE TRUE # - attr(*, '.lfref')=ĭF_1 <- as.ame(DT_1) # Coerce to a ame Str (DT_1 ) # Display the structure of the data # Classes ‘data.table’ and 'ame':Ĕ obs.
