similar to: Replacing dates with consecutive observations

I haven't used R in a couple of years, and now am trying something as simple as importing a csv file and am running into problems right away. * mydata <- read.csv (Wordata1.csv, sep="") Error in read.table(file = file, header = header, sep = sep, quote = quote, : object 'Wordata1.csv' not found *I've tried in both as as read.csv and read.table and still get the

My question is probably pretty basic, but since I'm really new to R, here it goes .... I have two separate data frames that include class names and various other information on classes. I'm trying to create a match based on class names and if a match exists to create a third data frame with the class name. I was hoping to accomplish this with sapply, but I can't figure out if I can

I'm trying to convert data from character to numeric. I've imported data as a csv file, I'm assuming that the import is a database - are all the columns in a database considered "vectors" and that they can be operated on individually Therefore I've tried the following mydata <- as.numeric(mydata$apples) when i then look at mydata again the named column is still

I'm trying to create a colored map that would show the number of students per state. My data frame consists of two columns - state and count. I'm using the following code library(maps) map("usa") library(plotrix) state.col<-color.scale(gre$count,0,0,c(0,1)) map("state",fill=TRUE,col=state.col) I'm getting a map, but the values are not being mapped to correct

I'm running the following code numbers <- 1:50 for (i in 1:50) assign(paste("model",numbers[i]),i)<-(lm(temp$Overall.Scaled.Score~temp$raw.score)) where I want R to create 50 different models-1:50, but get the following error message "target of assignment expands to non-language object". I've tried it with

I'm trying to create a fairly basic map using R. What i want to get is the map of the country with circles representing a count of students in each state. What I've done so far is as following - map("state") symbols(data1$count,circles=log(data1$count)*3,fg=col,bg=col,add=T,inches=F) this gives me the map of the country, but one that's not populated by my counts. Does

I've created a number of models using lm and now want to pick one with the smallest standard error or the smallest RSS, I can get a list of RSS using anova function, but is the any way I can then select one with the smallest RSS from the list? [[alternative HTML version deleted]]

I am trying to overlay a data frame with lat and longitude(which refer to zip codes) on the map of US that I get by using map ("states"). Is there anyway to do this or do I have to resort to using maptools? thank you [[alternative HTML version deleted]]

Hi everyone. I have two questions. I’ve found some other questions and answers similar to these but they didn’t solve my problem. I’m working with a panel of firm/years observations (see my reproducible example). I’m using the plm package. My panel not only is unbalanced but also have some gap’s in years. #reproducible example

Dear R-user, a few weeks ago I consulted the list-serve with a similar question. However, my task changed a little but sufficiently to get lost again. So I would appreciate any help on the following issue. I use the plm package and work with firm-level data in a panel. I would like to eliminate all firms that do not fulfill the requirement of having an observation in every variable used for at

I have a long sequence of dates, about 6 years worth, as one column in a data frame. How can I test whether the sequence is consecutive, that is, without gaps? Thanks. --Chris -- Christopher W.

I would like to connect the dots based on when they occur in time. Is there an easy way to do this? thanks f <- (structure(list(date = structure(c(1L, 2L, 3L, 10L, 11L, 12L, 13L, 14L, 15L, 16L, 17L, 18L, 19L, 4L, 5L, 6L, 7L, 8L, 9L, 2L, 3L, 10L, 13L, 14L, 15L, 16L, 17L, 18L, 19L, 4L, 5L, 6L, 7L, 9L ), .Label = c("1/1/03", "1/1/04", "1/1/06", "10/1/02",

Hi, I wanted to give a heads-up that I've been looking into replacing the AliasSetTracker(AST) with MemorySSA in the Loop Invariant Code Motion (LICM) pass. I would love to get feedback on the best way to incrementally push in this change. Motivation: There has been an outstanding issue with using the Alias Set Tracker due to its expensive construction time (quadratic). We've had test

In the file MkRules.local.in, I see the line: USE_ATLAS = NO which I believe needs to be changed to YES. But how do I specify the BLAS file *libopenblas_haswell-r0.2.20.a *and its location?

Hi all, After a long ride, I'm planning to turn on the use of MemorySSA for loop passes (D58311 <https://reviews.llvm.org/D58311>) tomorrow (8/29). Please let me know if you have issues, concerns or feedback on this. Best, Alina -------------- next part -------------- An HTML attachment was scrubbed... URL:

I suppose that, as expected, it's invalidated less often this way. Given that it's generally stateless, does this really represent a cost savings?  -Hal > > Thank you, > Alina > > > On Mon, Feb 10,

Hi Avraham, What a coincidence, I have been following this post of yours: https://www.avrahamadler.com/2013/10/24/an-openblas-based-rblas-for-windows-64-step-by-step/ Looks like this post is slightly older than what you have shared previously. It is strange that you did not get the attachments. I am pasting the contents of the MkRules.local here:
