Thank you Rui. I ran the following script df1 <- read.table("solar_hour", header = TRUE) df1$date <- as.Date(paste(df1$year, df1$hour), format = "%Y %j", origin = "2012-08-01-0") df2 <- df1[c("date", "IMF", "SWS", "SSN", "Dst", "f10")] head(df1) #To display all the rows print(df2). It gave me this

Here is the script I used to plot the graph indicating the text I wanted to insert. The line in the script that I have issues with is: text(-8,-8, "R^2= 0.62", r = 0.79, N = 161", cex = 2 R^2= 0.62 is not producing R squared = 0.62. Thanks. Sys.setenv( TZ="GMT" ) dt <- read.table("CLMXAPTY_sim", col.names = c("FDcli", "FDapt"))

Hi, the command line with 'text' should be: text(-8,-8, expression(R^2 * " = 0.62, r = 0.79, N = 161"), cex = 2 ) Best, Kimmo su, 2024-02-04 kello 17:16 +0100, Jibrin Alhassan kirjoitti: > Here is the script I used to plot the graph indicating the text I > wanted to > insert.

Hi Elo, It gave this error message: CR_plot2.R:14:37: unexpected string constant 13: plot(FDapt,FDcli, pch = 16, cex.lab = 1.6, cex.axis = 1.4, cex.main = 0.8, font.lab = 1.7, font.axis = 1.7, col = "red",main = "Simultaneous Events at CLMX and APTY",ylab="CLMX",xlab="APTY") 14: text(-8,-8, "expression(R^2*"= 0.62"), r = 0.79, N =

I have done a scatter plot in R. I want to insert the coefficient of determination R^2 = 0.62 as a text in the plot. I have tried to write R^2 but could not produce R2. I would appreciate it if someone could help me with the syntax. I have tried: expression(paste("", R^2,"=", 0.62)), but it did not produce R squared, rather it gave me error messages. Thanks.

Thank you Zhao for the code. When I replotted the graph after inserting the code in my script, it gave me this error message without plotting the graph: Warning message: In lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : extra argument ?col? will be disregarded.

In trying to use as.Date(), I've come across the conversion of POSIXlt to POSIXct when a POSIXlt variable is included in a data frame: my_POSIX <- strptime(c("11-09-2006", "11-10-2006", "11-11-2006", "11-12-2006", "11-13-2006"), "%m-%d-%Y") str(my_POSIX) my_Date <- as.Date(my_POSIX) str(my_Date) data <- format(my_Date)

Hi, i'm using this command line with EMD package filename<-emd(y,x,boundary="wave",plot.imf=F) i'd like to know if this EMD uses default values for non-specified arguments. i'm especially interested in "stoprule", "max.imf", "tol" behavior in such cases. Thanks

Dear R Users - R is a wonderful software package. CRAN provides a variety of tools to work on your data. But R is not apt to utilize all the public databases in an efficient manner. I observed the most tedious part with R is searching and downloading the data from public databases and putting it into the right format. I could not find a package on CRAN which offers exactly this fundamental

RFC: A proposal for vectorizing loops with calls to math functions using SVML (short vector math library). ========= Overview ========= Very simply, SVML (Intel short vector math library) functions are vector variants of scalar math functions that take vector arguments, apply an operation to each element, and store the result in a vector register. These vector variants can be generated by the

Hi Sanjay, For sincos calls, I’m currently just going through isTriviallyVectorizable(), which was good enough to get things working so that I could test the translation. I don’t see why this cannot be changed to use addVectorizableFunctionsFromVecLib(). The other functions that I’m working with are already vectorized using the loop pragma. Those include sin, cos, exp, log, and pow. From: Sanjay

R-help, I'm getting some unexpected behavior with subsetting a data frame (aircraft flight data) that I can't sort out. Here is a simplified version of my data frame and problem: > flight FlightID TailNo FlightDate HobbsTime FlightCost Date year 1 4497 6009K <NA> 2.2 330.0 <NA> NA 2 4498 6009K <NA>

Using: untrace(methods::conformMethod) at <- c(12,4,3,2) str(body(methods::conformMethod)[[at]]) ## language omittedSig <- omittedSig && (signature[omittedSig] != "missing") cc <- 0L trace(methods::conformMethod, tracer = quote({ cc <<- cc + 1L print(cc) if (cc == 31) { ## manually identified untrace(methods::conformMethod)

Hi all! It's my first message on this ML. I just installed Fedora Core and I had a small problem... kernel + initrd do not fit in a 1.44 disks... I looked at documentation and at code (kernel.inc) and I saw that syslinux - load kernel - load initrd - boot kernel So perhaps a small workaround for above problem should be to add a configuration to initrd (ie initrd=@initrd.img) to just ask to

Dear helpeRs, a colleague of mine would like to give R a try. He uses econometric models which typically involve a large number of variables, esp. time series. Having no experience with handling very large data sets myself I turn to you. 1. Could you please describe your experiences to cope with these situations? 2. What kind of difficulties will he have to face? Are there special
