Re: [R] Assigning several lists to variables whose names are contained in other variables

Hello, I believe that the point we are missing is that datatable$column stores the *names* of the graphs, not the graph objects themselves. So in the loop the objects must be retrieved with mget() or get(). First create a reproducible example. library(tidygraph) my_function <-

Re: [R] Assigning several lists to variables whose names are contained in other variables

I freely admit that I do not understand what you mean. But it sounds like you are trying to make things more complicated than necessary. Perhaps this little example may help clarify the issues: > a <- 1; b <- 2; d <- c(3,5) > stuff <- lapply(list(a,b,d),function(x)x^2) > stuff [[1]] [1] 1

Re: [R] Assigning several lists to variables whose names are contained in other variables

As I wrote before, I calculate tbl_graph objects, which will be joined afterwards. Not too much, the number of graphs to calculate is in the range between 5 to 20. Further steps are not automated, because they depend on how the single graphs look like, and which of them will be joined. For

Re: [R] Assigning several lists to variables whose names are contained in other variables

David, I don't think that this is the case. When I do the calculation like this subnet_MYSUBNET <- my_function(MYSUBNET), i.e. assigning a variable by hand to each function result, all is fine. Am 9. April 2021 17:22:05 MESZ schrieb David Winsemius : > >On 4/9/21 5:21 AM, Wolfgang Grond

Re: [R] Assigning several lists to variables whose names are contained in other variables

Folks, first of all - thanks a lot for your hints! I will try each again and think about, why I get error messages. But to resume: if I understand you right: there is no way to do something like this: $name = $result? Regards Wolfgang Am 9. April 2021 15:43:27 MESZ schrieb Rui Barradas :

Hello, my_function seems to be a function you have defined somewhere in your code. In your original post you mention it 3 times, this is the first one: subnet_MYSUBNET <- my_function(MYSUBNET) So Ivan's and Greg's code should work, they use a function you haven't posted but is assumed to

[R] Assigning several lists to variables whose names are contained in other variables

Dear all, I'm creating a list (which is a tbl_graph) by a function, and assign the result to a variable: subnet_MYSUBNET <- my_function(MYSUBNET) # MYSUBNET: a tbl_graph Because there are multiple subnets to create, I can get the names of the subnets (MYSUBNET1, MYSUBNET2, MYSUBNET3, etc.)
