In game theory, the Shapley value of a player is the average marginal contribution of the player in a cooperative game. That is, Shapley values are fair allocations, to individual players, of the total gain generated from a cooperative game.

Step 1) Earlier in the tutorial, we stored the columns name with the missing values in the list called list_na. We will use this list. Step 2) Now we need to compute of the mean with the argument na.rm = TRUE. This argument is compulsory because the columns have missing data, and this tells R to ignore them.Updated Jan 2023 · 32 min read.

Running names (token) returns NULL. Running str (token) shows the problem: the first attribute is NULL and the second is the one I want as its name.III. Alternative solutions without using apply(). Although the OP specifically asked for a solution with apply(), alternative solutions were suggested.For example, the answer of @George Petrov suggested to use map(); the answer of @Thibaut Dubernet proposed assign().. I fully agree that apply() is seldom the best solution, because …In this post we’ll cover the vapply function in R. vapply is generally lesser known than the more popular sapply, lapply, and apply functions. However, it is very useful when you know what data type you’re expecting to apply a function to as it helps to prevent silent errors. Because of this, it can be […] The post Why you should use vapply in R appeared first on Open Source Automation.a replacement for matched pattern in sub and gsub. Coerced to character if possible. For fixed = FALSE this can include backreferences "\1" to "\9" to parenthesized subexpressions of pattern. For perl = TRUE only, it can also contain "\U" or "\L" to convert the rest of the replacement to upper or lower case and "\E" to end case conversion.The apply function takes data frames as input and can be applied by the rows or by the columns of a data frame. First, I’ll show how to use the apply function by row: apply ( my_data, 1, sum) # Using apply function # 6 8 10 12 14. As you can see based on the previous R code, we specified three arguments within the apply function: The name of ...sapply is a command in the R language that applies a function to each element of a vector (atomic or list). It may also accept other classes if they are coercible by the function base::as.list. The sapply function returns a vector by default, however will return a list when more suitable or an array if argument simplify = "array" is specified.Return a matrix or an array. The output of the sapply function in R can also be a matrix or an array. On the one hand, if the function you are applying returns vectors of the same length, the sapply function will output a matrix where the columns are each one of the vectors.Option 1: Consider using stringi. Even splitting, converting to a matrix, and extracting the first column of the matrix is faster than the solutions I came up with in base R: Option 2: Consider using sub with a perl regular expression: Option 3: Prefer vapply to sapply, and help strsplit out by adding fixed = TRUE:Feb 11, 2014 · I am using R and have searched around for an answer but while I have seen similar questions, it has not worked for my specific problem.

lapply vs sapply in R. The lapply and sapply functions are very similar, as the first is a wrapper of the second. The main difference between the functions is that lapply returns a list instead of an array. However, if you set simplify = FALSE to the sapply function both will return a list. To clarify, if you apply the sqrt function to a vector ...Example 1: Sum Values in Vector. The following code shows how to sum the values in a vector: #create vector x <- c (3, 6, 7, 12, 15) #sum values in vector sum (x) [1] 43. If there happen to be NA values in the vector, you can use na.rm=TRUE to ignore the missing values when calculating the mean:
