[R] what happened to inside-r? [possibly OT]

This might be a bit off-topic, but up until recently (a day or so ago?) I loved using inside-r.org as a quick and easy way to access help pages on R commands. Took me to what I needed without any fuss. Now that URL redirects to the "Microsoft R Application Network"? Looks to be something

[R] dplyr or plyr or both?

I've set myself the task of learning about these packages, and about tidy data concepts. What is the relationship between plyr and dplyr? Does the latter replace the former (meaning I can concentrate on learning the latter)? Or is there ever a need to use functions from both (meaning I should

Re: [R] dplyr or plyr or both?

I have the impression that it is also possible to library dplyr after plyr, but it is better to remove plyr! This is a serious problem that has been reported before, but not solved (in dplyr 0.5.0 and plyr 1.8.4) Frams 2016-09-15 16:09 GMT+02:00 Christopher W Ryan <cr...@binghamton.edu <mailto:cr...@

[R] trouble with starting date in sts and disProg objects in the surveillance package

I create a data frame, then, using package surveillance version 1.3, I convert it to a surveillance time series (sts) object and then to a disProg object. But in the plot of the disProg object, the dates seem to be mislabelled? Grateful for any advice. --Chris Ryan Broome County Health

Re: [R] Help

Leonardo-- R-help can be a very useful resource. Some suggestions to use it well: 1. use an informative subject line, not "help" 2. include a "minimal working example:" a *little* data, the code that, with those data, reproduces your problem, and the error message that resulted. As to your

Re: [R] How to Transform a Factor Variable into a Date

A couple thoughts: 1. converting factors into dates often requires that they be converted to character first. 2. you don't really have dates; you have just months and years 3. therefore perhaps the as.yearmon() function in the zoo package could help library(zoo) my.factor <- factor("Feb 2017")

Re: [R] about fitting a regression line

Rather than just posting your error message, it helps immensely to post the code that produced the error--indeed with some small sample data that reproduces the problem. x <- rnorm(40) y <- 0.6 * x + rnorm(40, sd = 0.3) plot(y ~ x) model <- lm(y ~ cos(x)) summary(model) plot(y ~ cos(x))

Re: [R] Data cleaning & Data preparation, what do R users want?

Great question. What do I want? I want my co-workers to stop using Excel spreadsheets for data entry, storage, and sharing! I want them to understand the value of data discipline. But alas . . . . I work in a county health department in the US. Between dplyr, stringr, grep, grepl, and the base R

[R] printing an arbitrary-length character vector in columns on a page of a pdf report

I'm writing code for a recurring report, using an R --> Sweave --> pdflatex workflow. It includes a character vector of short words that I would like to display compactly, in columns on a page, rather than one word per line, which would waste a lot of space. The vector of words will increase

Re: [R] printing an arbitrary-length character vector in columns on a page of a pdf report

Richard-- Nice. If I understand your code correctly, in the line ddm <- matrix("", (n+2) %/% nc, nc) I could instead use ddm <- matrix("", (n + nc - 1) %/% nc, nc) for generalizability, as I may have to increase nc as the list of words grows ever longer. Thanks everyone. Several good

[R] How would I color points conditional on their value in a plot of a time series

How would I color points conditional on their value in a plot of a time series. Something like this: ## demonstration data ttt <- ts(rpois(12, lambda = 8), start = c(2000, 1), freq = 4) ttt plot(ttt, type = "p") ## doesn't work--all points the same color plot(ttt, type = "p", col = ifelse(ttt <

Alas, we spend so much time and energy on data wrangling . . . . I'm given a collection of csv files to work with---"found data". They arose via saving Excel files to csv format. They all have the same column structure, except that some were saved with column names and some were not. I have a
