vegas | Vegas aims to solve the simple problem

The reason for the error is that there is no 8 and there are 2 12s.

I was not able to figure out how to do this with "visIgraph()" function - but I think I was able to figure out how to generate a random graph (meeting certain conditions: Generating Random Graphs According to Some Conditions) and using the regular "visNetwork()" function and then place a title on this graph:

Not sure to fully understand what you are looking for but:

1. If you want the vertices to be placed randomly and not on a circle, you just need to use the argument layout = "layout_randomly" inside the visIgraph() function.

2. If you want the vertices to be placed randomly and on a circle, you need to use the permute() function and then just add the argument layout = "layout_circle" inside the visIgraph() function.

You don't want NOLOCK here, that is the exact opposite of what you need, as it may miss or double-count rows in many high-concurrency situations. You need more locking. I suggest you use SERIALIZABLE for iron-clad guarantees.

You would need an explicit transaction for your current code. But this does not actually need it, because you can do it all in one statement (every statement runs in its own transaction anyway).

You can use this example how to load the data into a DataFrame:

Use nunique:

Pass a list with strings of the columns, i.e.

It seems that the spread_table after scraping may be post-processed in a way that couldn't convert the extracted substring into numeric class - i.e. when we do as.numeric, if there is any character, it may convert to NA.

In the below code, select the columns of interest after scraping, then extract the substring from the 'game_info' column to split into 'date', 'time', 'away_team_name' and 'home_team_name' based on a regex pattern matching and capturing ((...)) those groups that meet the criteria. (^(\\S+)) - captures the first group as one or more non white spaces characters from the start (^) of the string, followed by one or more white space (\\s+), then capture characters that are not newline character (([^\n]+)) followed by any character that is not letter ([^A-Za-z]+), capture third groups as one or more characters not the newline followed by again the characters not a letter and capture the rest of the characters ((.*)). Then loop across the 'BetMGM' to 'FanDuel', extract the substring characters not having u or - and is followed by a space ((?=\\s)), replace the substring fraction with + 0.5 (as there was only a single fraction), loop over the string and evalutate the string
