User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

User: kann ich in r mit der funktion pivot_long auch mehrere spalten nehmen bei names_to=
Assistant: Ja, in R können Sie mit der Funktion `pivot_longer()` aus dem `tidyr`-Paket mehrere Spalten gleichzeitig verwenden, indem Sie den `names_to`-Parameter spezifizieren. Der `names_to`-Parameter gibt an, wie die Namen der ursprünglichen Spalten in der neuen, langen Tabelle zugeordnet werden sollen. Wenn Sie mehrere Spalten in `names_to=` angeben möchten, können Sie eine Zeichenkette oder ein Vektor von Namen verwenden, um die Zielspaltennamen anzugeben.

Hier ein Beispiel:

```r
library(tidyr)

# Beispiel-Datenrahmen
df <- data.frame(
  id = 1:3,
  group_1 = c(10, 20, 30),
  group_2 = c(40, 50, 60)
)

# Pivotieren mit mehreren Spalten in names_to
df_long <- pivot_longer(df, 
                        cols = starts_with("group"), 
                        names_to = c("variable", "group"),
                        names_sep = "_")

print(df_long)
```

In diesem Beispiel wird der `names_to`-Parameter verwendet, um zwei neue Spalten (`variable` und `group`) zu erstellen, und `names_sep = "_"` gibt an, bei welchem Zeichen die ursprünglichen Spaltennamen gesplittet werden sollen. Dies ermöglicht es, die Datenspalten aus dem Weitformat in das Längsformat umzuwandeln, während mehrere Teile des Spaltennamens auf verschiedene Zielspalten gemappt werden.
User: Wie kann ich das datum hier trennen hw %>% pivot_longer('price_2012-01-01':'quantity_2015-01-01',                      names_to = c("year", "month", "day", "price", "quantity"),                      values_to = "price", names_sep = "_")
