Example 1: Convert List to Data Frame ColumnsIf we want to convert each of the two list elements to a column, we can use a combinations of the cbind, do.call, and as.data.frame R functions:as.data.frame(do.call(
Assuming your list of lists is called l:df <- data.frame(matrix(unlist(l), nrow=132, byrow=T))he above will convert all character columns to factors, to avoid this you can add a parameter to the data.frame() call:df <- data.frame(matrix(unlist(l), nrow=132, byrow=T),stringsAs...
To convert List to Data Frame in R, call as.data.frame() function and pass the list as argument to it. In this tutorial, we will learn the syntax of as.data.frame() function, and how to create an R Data Frame from a List, or convert a given list of vectors to a Data Frame, ...
下面的方式优雅,和jsonlite::fromJSON一致,能将嵌套列表转为嵌套数据框: data_frame <- as.data.frame(do.call(cbind, nested_list)) https://www.geeksforgeeks.org/convert-nested-lists-to-dataframe-in-r/www.geeksforgeeks.org/convert-nested-lists-to-dataframe-in-r/编辑...
}# Convert list into data frameas.data.frame(all) } 测试读入的数据来自ggplot2包: library(ggplot2) write.csv(diamonds,"diamonds.csv", row.names = FALSE) 使用lineprof时,需要以下几个步骤,首先使用source(),将源代码加载进内存,然后用lineprof()包含调用的语句,最后shine()展示返回的结果。需要注意的...
Example: Convert Time Series to Data Frame Using as.data.frame() FunctionThis example demonstrates how to change the class of a time series object to the data.frame class.For this task, we can apply the as.data.frame function as shown below:...
