Can't get function to work with current season data

[WobblyOG]

Hello, I'm trying to create a function that takes a vector of player names as an input and outputs a dataframe of their week by week scores using get_player_info(). The function works if I specify season = 18 but I can't get it to work for the current season.

Here's the code that works: fn = function(team){ df <- data.frame(matrix(ncol = 0, nrow = 38)) for(i in team){ points = get_player_details(name = i, season = 18)$total_points df[,i] = points } return(df) }

df1 = fn(team)

but removing season = 18 and changing nrow to 29 (29 gameweeks) gives me this error:

Error in [<-.data.frame(*tmp*, , i, value = c(0L, 1L, 0L, 1L, 3L, : replacement has 28 rows, data has 29

I'm new to R and I can't quite figure out why. Any help would be appreciated! Thanks :)

Hi, sorry for getting to this so late, I missed it. There will be some variance in how many games different players have played, so you don´t want to restrict your matrix to a specific number of rows.

Your solution is also a bit too complex - there´s no need to loop, so here´s an alternative that should work:

# define the players you want to get data on. Can do this manually as here, or through a function
players = c("Virgil van Dijk", "Andrew Robertson", "Trent Alexander-Arnold")

# grab the player IDs using the get_player_id() function
playerids = get_player_id(players)

# grab the player details
df = get_player_details(playerids$id)

# select the total_points column.
df$total_points

# or if you want a data frame with player names, round and gameweek score (requires dplyr):
df %>% select(playername,round,total_points)

Again sorry for the slow reply. Hope this is still helpful.

Closing - resolved.
