    What is the difference between a sequential program and an event-driven program?

    elveralowe

    Two different methods to support two different needs. An event-driven approach is best for problems that are driven by events. You will want to use a “sequential” approach if you are unable to control what is happening in the world. These two things will often be combined. The startup and shutdown oRead more

    Two different methods to support two different needs. An event-driven approach is best for problems that are driven by events. You will want to use a “sequential” approach if you are unable to control what is happening in the world.

    These two things will often be combined. The startup and shutdown of a program, as well as a main processing loop (say, a filter process in an image app), will all be largely sequential. However, its UI layer, component interactions, and event-driven UI layers will be largely sequential.

    Stabilizing the error: could not find function “%>%” with the best answers

    You need to load the package magrittr or dplyr that defines the function. Then it should work.

    install.packages("magrittr") # package installations are only needed the first time you use it
install.packages("dplyr")    # alternative installation of the %>%
library(magrittr) # needs to be run every time you start R and want to use %>%
library(dplyr)    # alternatively, this also loads %>%

    %>%, a pipe operator, was created to “decrease development times and improve the readability and maintenance of code. ”

    This code does not use the pipe %>%. It would return the exact same code as yours: 

    words <- colnames(as.matrix(dtm))
words <- words[nchar(words) < 20]
words

    Maybe you are interested in ifelse a <- c(1,1,1,1,0,0,0,0,2,2) ifelse(a>0,a/sum(a),1) [1] 0.125 0.125 0.125 0.125 1.000 1.000 1.000 1.000 [9] 0.250 0.250

    Maybe you are interested in ifelse

    a <- c(1,1,1,1,0,0,0,0,2,2)
ifelse(a>0,a/sum(a),1)

    I ran across the same problem in a Widget Target, but it was solved when I added "public" to the variables. The program after fixing is: struct LastCommitEntry: TimelineEntry { public let date: Date public let commit: Commit }
