Re: [R] lag.plot showing only lines....

Hi Akshay, I have never used this function before but according to ?lag.plot you simply need to pass the argument do.lines=FALSE. HTH, Eric On Mon, Aug 28, 2023 at 5:45 PM akshay kulkarni wrote: > > Dear members, > I am using the following code: > >

[R] lag.plot showing only lines....

Dear members, I am using the following code: lag.plot(ygrpch(OHLCData[[i]]),lags=4) But instead of dots, it is showing lines, which I don't know how to interpret. How to make it plot dots? This is working properly: lag.plot(na_interpolation(OHLCData[[i]][,4]),lags=4)

[R] Book Recommendation

Good Morning, I am doing some research to develop a new course where I teach. I am looking for a book to use in the course content to teach accomplishing SQL in R. Does anyone know of a book on this topic to recommend for consideration? Thank You, -- *Stephen Dawson, DSL* /Executive

Re: [R] Book Recommendation

I presume you are familiar with the RSQL and RSQLite packages and their vignettes. Can't offer any help, but a point of clarification: When you say, "teach accomplishing SQL in R," do you explicitly mean using SQL syntax in R to manipulate data or do you mean just doing SQL-like types of data

Dear R-Users, Just out of curiosity: Which of the 2 methods is the better one? The results seem to differ slightly. fun = function(u){((26104.50*u^0.03399381)/((1-u)^0.107)) - 28353.7} uniroot(fun, c(0,1)) # 0.6048184 curve(fun(x), 0, 1) abline(v=0.3952365, col="red")

Thanks, Bert. I appreciate your helpful assistance. This is an academic course. The effort now is to nail down the former. I am pushing against a local db for the students. I prefer they focus on the get-and-analyze efforts and not db administration efforts. Kindest Regards, *Stephen

Re: [R] Book Recommendation

These days I'd recommend duckdb (https://cran.r-project.org/web/packages/duckdb/index.html) instead. It's a similar design to RSQLite (i.e. you don't need a separate server) but it's designed for the needs of data science. Hadley On Tue, Aug 29, 2023 at 9:22 AM Martin Møller Skarbiniks Pedersen
