"Object '...' not found when referenced object is a nested function in R


"Object '...' not found when referenced object is a nested function in R

it should still fix some issue
Is there some way to define a variable that's a function before the function definition?
code :
frqTbl <- function(df){

  fctvr <- df[sapply(df,is.factor)]
  logicvr <- df[sapply(df,is.logical)] 
  nwDf <- data.frame(fctvr,logicvr)

  if(ncol(nwDf)>0){ 

    freq <-list() 
    for (i in 1:ncol(nwDf)){ 

      freq[[i]] <- as.data.frame(table((nwDf)[,i]))
      names(freq[[i]])[1]=colnames(nwDf[i])
    } 
    return(freq)
  }
  else{
    print("There are no categorical or logical variables in the data   
            frame.")  
  }
}

rSqd <- function(df){

  y <- df[sapply(df,is.numeric)] 

  if(ncol(y)>=2){ 

    c <- combn(colnames(y), 2) 

    vrPrs <- paste(c[1,], c[2,], sep = "-")

    m <- cor(y, method = "pearson")

    r <- m[which(lower.tri(m))] 

    vlus <- r^2

    df2 <- data.frame(vrPrs, vlus)

    names(df2) <- sub("^vrPrs$", "Variable Pairs", 
                      names(df2)) 
    names(df2) <- sub("^vlus$", "R-Square", names(df2))


    format.data.frame(df2) 
    return(df2)

  }
  else{
    print(paste("This Data Frame does not have two or more numerical  
            columns to compute the Pearson correlation coefficient(s)."))
  }
}

mstrFnct <- function(df){

  output <- list()
  output[[length(output)+1]] <- frqTbl(df)
  output[[length(output)+1]] <- rSqd(df)

  return(output)
}

data(diamonds, package = "ggplot2")
test <- diamonds[1:100,]
mstrFnct(test)
mstrFnct <- function(df){

  # create output list
  output <- list()

  # define function frqTbl()
  frqTbl <- function(df){

    fctvr <- df[sapply(df,is.factor)]

    nwDf <- data.frame(fctvr,logicvr)

        freq[[i]] <- as.data.frame(table((nwDf)[,i]))
        names(freq[[i]])[1]=colnames(nwDf[i])
      } 
      return(freq)
    }
    else{
      print("There are no categorical or logical variables in the data   
          frame.")  
    }
  }

  # call function frqTbl() and store result in list
  output[[length(output)+1]] <- frqTbl(df)

  # define function rSqd()
  rSqd <- function(df){

    y <- df[sapply(df,is.numeric)] 

    if(ncol(y)>=2){ 

      c <- combn(colnames(y), 2) 

      vrPrs <- paste(c[1,], c[2,], sep = "-")

    else{

            columns to compute the Pearson correlation coefficient(s)."))
    }

Hope that helps Try using find() to find the span tag in the h1 as stated in the docs:
$(this).find('span')

may help you . You need to ensure that all repositories are using the same context for atomic operations. so you need to create your context and pass that into your repositories in the constructor. Something like this:
code :
var ctx = new ApplicationDbContext();
var playerRepository = new PlayerRepository(ctx);
var userPropertiesRepository = new UserPropertiesRepository(ctx);
when creating an object inside of an object and then adding to the nested object the console only returns "object&q

help you fix your problem I am trying to create some nested objects with values inside of them. I have the following code: , You may use JSON.stringify:
code :
var bob = {name: "Bob Smith", age: 30};
bob.location = 'new florida';
bob.favoriteFood = {};
bob.favoriteFood.american = 'pizza';
bob.favoriteFood.european = 'not pizza';

console.log(JSON.stringify(bob));

I wish this helpful for you If the structure never changes, IE; ImageObjects.LANGUAGE.project.keywords, this will suffice:
code :
function detectProjectByKeyword(keyword, obj, language) {
  for(var a in obj[language]) {
    if(obj[language].hasOwnProperty(a)) {
      if(obj[language][a].keywords.indexOf(keyword) >= 0) return obj[language][a]
    }
  }
}

console.log(detectProjectByKeyword('brumi', ImageObjects, 'DE'));
console.log(detectProjectByKeyword('lkws', ImageObjects, 'DE'));
console.log(detectProjectByKeyword('mautmaxe', ImageObjects, 'DE'));

like below fixes the issue If I have an object todo as part of your state, and that object contains arraylists, inside the lists there are objects, and inside these objects another arraylistItems. How do you update an object inside the array listItems with id:" poi098 "? , You can update your nested array as,
code :
this.setState(prevState => ({
   ...prevState,
   todo: {
      ...prevState.todo,
      lists: prevState.todo.lists.map( list => ({ 
        ...list,
        listItems: list.listItems.map( listItem => listItem.id === data.id ? data : listItem )
      }))
   }
}))
