dear Members, I have recently started studying SQL and MySQL. My question is, what exactly is SQL used for? That is, whatever can be done by SQL, like subsetting and filtering of data sets, can also be done by R. What's, then, the advantage of SQL? It is OK if you tag this question as offtopic, but I could'nt find any info on the web. Can you please refer me to

Just a slight technical note -- Ben gave you a good answer already, imo. The note is: R is Turing complete, which mean that *anything* any language can do, R could be programmed to do also. The point is what can be done well in R and what can be done (often much) better with other tools, as Ben explained. Cheers, Bert On Wed, Dec 11, 2024 at 5:17?AM akshay kulkarni <akshay_e4 at

The advantages of SQL are that - it can be used from many languages so if you know SQL you can easily move that part of your code to python, say, and visa versa - it is widely used - it can handle data stored outside of R and possibly otherwise too large for R - some SQL databases support multiple concurrent users - depending on the database it may be used to communicate the data to others - one

Dear Askay, I believe my grey hair allows me to help answer your question. SQL, and its progenitor SEQUEL, were developed specifically to manipulate relational databases. It was developed in the early 1970s (equivalent to the historical bronze age) when the concept of a relational database (see https://en.wikipedia.org/wiki/Relational_database) and Codd's 12-rules were being developed (see

And to answer the dependency question. Neither is dependent on the other. But both can be complimentary. If you consider that SQL*may* be a route to accessing your data (if it's in a database). And R *may* be a route to analysis of the data. If the data is in a CSV file, Excel file, API etc. you don't need SQL. IF it is in a database, you might extract it to CSV etc. or you might

My late friend Morven Gentleman, not long after he stepped down from being chair of Computer Science at Waterloo, said that it seemed computer scientists had to create a new computer language for every new problem they encountered. If we could use least squares to measure this approximation, we'd likely be suspicious of a terribly small error measure or overly high R^2. JN On 2024-12-11

Akshay, Your question has way too many answers. SQL has a long history and early versions came long before R arrived on the scene. There is a huge embedded base of hardware and software dedicated to managing databases. It has some features that most R programs do not even dream of doing. Besides easily handling massive amounts of data or sometimes tweaking queries to possibly run more

Dear members, I am using caret for modelling my data. It is a regression problem. My question is : how to plot the final model on the actual data points? The output of the model will be a nonlinear form of the activation function; I want to plot it on the data points. I have researched on web but to no effect. Like drawing a line on the original data points, for a

I have done some searching on the Internet, but not been able to find a solution to my problem. I hope you can help me with this. I have a server at home that runs on FreeBSD 10.3. The file system is ZFS. I have two ZFS pools: tank and fun. I share my ZFS file systems using Samba v4.6.2. When I add recycle bin functionality for a share like below, it work like a charm: [mac] path =

Hi I hope this was not asked before. What methods can be used to secure the "tinc" config files? If for example using a VPS provider like digital ocean , how can one be sure that the local admins dont access your container and read the contents of the tinc config files? Is there a better solution , should full drive encryption be used and dedicated servers? Regards Yazeed Fataar

Hi Guus Can you recommend a good strategy in securely managing the config and hosts files please? <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> This email has been sent from a virus-free computer protected by Avast. www.avast.com

Dear R Staff You can see my data.csv file in the annex. I try to count non-zero values in dataset but I need to exclude NA in this calculation My code is very long (following), How can I write this code more efficiently and shortly? ## [NA_Count] - Find NA values data.na =sapply(data[,3:ncol(data)], function(c) sum(length(which(is.na (c))))) ## [Zero] - Find zero values

Thanks Guus So based of this , having your central tinc server in VPS Provider , will allow potentially the provider to replicate your config files and thus exposing all your remote sites connected. My situation I face is all my remote sites have dynamic addresses ,and in order for me to create a connection point between the sites is to have a central server in cloud with public address. Therefor

Oops, wrong language ;D Okay Rowland. Thank you very much for this help.

Thanks Guus.. So if someone had to gain access to my vm-disk. They would not be able to view the contents of the files in ""etc/tinc" if I do "sudo chmod go= /etc/tinc" .. My paranoia is around a VPS provider who had admin access to all containers. I know that I have to create a root password that will allow only myself root access , but im just worried about the disk

Good morning. I've ran a test against MP3 format.
