I have been searching high and low for what I think is an easy solution.
I have a large data frame that I split by factors.
eqRegions <- split(eqDataAll, eqDataAll$SeismicRegion)
This now creates a list object of the data frames by region; there are 8 in total. I would like to loop through the list to make individual data frames using another name.
I can execute the following to convert the list items to individual data frames, but I am thinking that there is a loop mechanism that is fast if I have many factors.
testRegion1 <- eqRegions[[1]]
testRegion3 <- eqRegions[[3]]
I can manually perform the above and it handles it nicely, but if I have many regions it's not efficient. What I would like to do is the equivalent of the following:
for (i in 1:length(eqRegions)) {
region[i] <- as.data.frame(eqRegions[[i]])
}
I think the key is to define region before the loop, but it keep overwriting itself and not incrementing. Many thanks.
Use the split() function in R to split a vector or data frame. Use the unsplit() method to retrieve the split vector or data frame.
Convert List to DataFrame using data. data. frame() is used to create a DataFrame in R that takes a list, vector, array, etc as arguments, Hence, we can pass a created list to the data. frame() function to convert list to DataFrame. It will store the elements in a single row in the DataFrame.
To split the above Dataframe we use the split() function. The syntax of split() function is: Syntax: split(x, f, drop = FALSE, …)
Try
list2env(eqRegions,envir=.GlobalEnv)
This should work. The name of the data.frames created will be equal to the names within eqDataAll$SeismicRegion
. Anyways, this practice of populating individual data.frames is not recommended. The more I work with R, the more I love/use list.
lapply(names(eqRegions), function(x) assign(x, eqRegions[[x]], envir = .GlobalEnv))
edit: Use list2env
solution posted. Was not aware of list2env
function.
