Example 4: Maxima & Minima Across All Columns You might be interested in the maxima and minima of all the columns of your data matrix. Of cause, you could apply the max and min R functions to each of the columns one by one. However, thesapply functionprovides a much smoother and automa...

Note that there are now summary rows for each year and that the columns have names. However, the PostCount column contains the number of rows in a given year, not the sum of the posts. To change this, I’ll need to use the sum function to add up the values in the Posts column. ...
“mean”, bouncing across the top of a data table applying the function to each column. Stylized text reads: “dplyr::across() - use within mutate() or summarize() to apply function(s) to a selection of columns!” An example shows the use within summarize: summarize(across(where(is....

It is expected that the minimum value should be0.5. So, if an anchor box has an IoU score that is greater than0.5but less than or equal to0.7, then assign it a positive objectness score. Assume that the IoU scores of an anchor are listed below. Because the highest IoU score is the ...
Use this option to find potential programming bugs. It invokes an extra compiler pass to check for consistency in subprogram call arguments, common blocks, and parameters, across the global program. The option also generates a line-numbered listing of the source code, including a cross reference ...

If higher than 0, you can find what columns are giving issues with sapply(as.data.frame(scale(df)), function(x)any(is.nan(x))) and sapply(as.data.frame(scale(df)), function(x)any(is.infinite(x))). Any column yielding TRUE will generate issues while trying to fit models with ...
