After converting, we can perform data manipulation and other operations as performed in a data frame. For example: library("XML") library("methods") #To convert the data in xml file to a data frame xmldataframe <- xmlToDataFrame("file.xml") print(xmldataframe) Output: ID NAME SALARY ...
Description – The Split() Function in R The split function in r is the function that you use to split data frames and vectors. It has the form of split(v, g) and it willsplit the dataframe or vector according to groups. In this function, v is thedata frameor vector and g is the...
First, we need to create an empty data frame that the new files will be added to. Then, we can use the for loop to import and bind them to this data frame. #Formula<dataframe name> <- data.frame()for (file in filelist){df <- <read function>(file)<dataframe name> <- rbind(<...
For simplicity and clarity, we’re going to start with a simple example of how to use case_when on an R vector. But since we commonly use case_when withdataframes, the remaining examples will show you how to use case_when on an R dataframe. You can click on any of the following li...

fread is a simpler function for reading a specified byte of data and then being able to call it back from our dataframe in a flash. Though simpler, there are still parameters to work inside to fully utilize the search tool and its multifunctionality, so let’s see how we can fully utiliz...
importzlibr.set("key", df.to_msgpack(compress='zlib')) Now our dataframe is set to Redis. To successfully get the DataFrame, we can either use theread_msgpack()method or we can import thepicklepackage which has the loads method which will help us to decompress the Zlib compression applie...
(for dataframe), “data”, or even “my_data”. You could use more explicit names such as “tennis_data” if you are using data on tennis matches for example. However, the main drawback with using specific names for datasets is that if, for instance, you want to reuse the code you...
