R Error In Match.funfun

Can you move a levitating target 120 feet in a single action? I would run my test harness which returned a matrix. file. Note that lapply doesn't have a margin argument as it simply applies the function to each of the variables in the data frame.

The function takes one argument, which I have arbitrarily called x.

Dirty Deeds Anyway, a cheap trick is to pass sapply a vector of indexes and write your function making some assumptions about the structure of the underlying data. Comments are closed.

  • As a commenter pointed out, if you are using a data frame the data types must all be the same otherwise they will be subjected to type conversion.
  • For example, let's look at the mean value of only the positive values: apply(m, 2, function(x) mean(x[x>0])) #[1] 0.4466368 2.0415736 4.8685779 Using sapply and lapply These two functions work in a
  • Let's have a look: apply(m, 2, function(x) is.matrix(x)) #[1] FALSE FALSE FALSE Not a matrix.
  • The y value will be the same for each call sapply makes to our function.

Yes, "some other function" since all those operations are vectorized, this could be more easily done with: mat[ ,1]*mat[ ,2]+a+b # and no need for a loop, right? -- David Fine for quickies but not very nice, and will likely turn into a maintainability bomb down the line.

The basic format is apply(array, margin, function, ...)

We can use apply and the base mean function to check this.

This may or may not be what you want, if the data frame has string/character data as well as numeric data, the numeric data will be converted to strings/characters and numerical You probably meant to use sapply instead. R will magically return the last evaluated value.

I don't really recommend passing the index arguments like this, it is error prone and can be quite confusing to others reading your code. Copyright © 2016 R-bloggers.

Peter Alspach -----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf Of Pfeiffer, Steven Sent: Friday, 25 July 2014 5:08 a.m. I have a dataframe with a column of strings. Sometimes we require traversal of our data in a less than linear way. There is a part 2 coming that will look at density plots with ggplot, but firstI thought I would go on a tangent to give some examples of the apply family,

A zero dimensional array is a scalar or a point; a one dimensional array is a vector; and a two dimensional array is a matrix… The margin argument is used to Always happy to make a small contribution to @Wikipedia. Baking at a lower temperature than the recipe calls for Why didn't Dave Lister go home? I am trying to replace negative values in an array with these values + 24.

All Rights Reserved. Please check out part 2 where we create a density plot of the values in our matrix. As an added bonus, match.fun() also allows you to use a character object as the argument, so specifying FUN = 'round' now works as well. However, today, I keep getting this error message: Error in match.fun(FUN) : argument "FUN" is missing, with no default help?
