export 3D array to .txt file
...I want to save it in a textfile. I want to be able to reload the text file to get the same array again: new.array<-load(mytextfile.txt) or something similar. I was not able to figure out a way to do that with write.table without having to save 200 text files. Is there another way? Thank you!

alternating element in url
...eds the URL to be in "". If I put read.table("url") R wont recognize it as the url I defined earlier. But I also do not know how to use cat() to get " at beginning and end. If I am approaching this in a totally dorky way (likely...), please let me know, too. Thank you!!

extracting data from unstructured (text?) file
...3.4/ 3.5 ... So I have two problems really: 1. How do I detect the table in the file (resp. the line where the table starts)? 2. How do I break up each line to write the values into a matrix? Feel free to suggest an entirely different approach if you think that is helpful. Thanks a lot!

correlating matrices
Hi, thank you for taking the time and reading my question. My question is twofold: 1. I have several matrices with variables and one matrix with water levels. I want to predict the water level with the data in the other matrices. Basically, * mod<-lm(matrix1 ~ matrix2+matrix3)* ( What looks like a minus is meant to be the wiggly minus.) Of course I could dissemble the matrices and paste

predict.lm if regression vector is longer than predicton vector
...orter than the orginial vector that I did the regression with. It gives you the following error: Warning message: 'newdata' had 365 rows but variable(s) found have 1825 rows Of course I can extend the new dataframe with a few thousands NAs, but is there a more elegant solution?

Filelocking Issue in 4.18.11
Hi Felix, On 4/18/24 08:33, Stolte, Felix via samba wrote: > Is this a bug or maybe a misconfiguration? In the latter, which parameters could cause this? I guess the nodes end up using different combinations of dev/inode as primary key for the locking.tdb record. Probably because the device numbers differ on the nodes and you didn't fix this known issue with GPFS with the fileid VFS

converting 3D array to a data-frame (with coordinate-columns x, y, z)
Hi, I am still struggling with three dimensional arrays. Now I would like to convert a three dimensional array into a data-frame with the coordinate-columns: x, y, z and a value-column. And I definitely don't want to loop over every element, since this would be very resource intensive for the actual data-set. Are there any specific functions that are helpful for this task?
