I'm trying to install the package 'Performance Analysis' in the R script below:
tryCatch(
expr = {
#library('PerformanceAnalytics', verbose = FALSE, quietly = TRUE)
library("PerformanceAnalytics",lib.loc=.libPaths(),verbose = FALSE, quietly = TRUE)
},
error = function(e){
print(e)
install.packages('PerformanceAnalytics', repos='https://cran.rstudio.com', verbose = FALSE)
#library('PerformanceAnalytics', verbose = FALSE, quietly = TRUE)
library("PerformanceAnalytics",lib.loc=.libPaths(),verbose = FALSE, quietly = TRUE)
}
)
But I'm having the following error message (Version 1.2.1335 of R Studio). Does anyone know if I've made a mistake somewhere?
Thanks

I can't get this dplyr package loading message to go away:
package 'dplyr successfully unpacked and MD5 sums checked
And here is my current code:
g <- df$Finished
h <- append(g, rep("dummy",519))
i <- data.frame(counts <- table(h))
row.names(i) <- c("In progress", "Completed", "Invited")
colnames(i) <- c("gh", "Count")
i = subset(i,select = -c(gh))
suppressPackageStartupMessages(install.packages("dplyr", repos = "http://cran.us.r-project.org", quiet = TRUE, message=FALSE))
suppressPackageStartupMessages(library(dplyr, quietly = TRUE, warn.conflicts = FALSE, invisible()))
ii<- i %>%
arrange(desc(Count))
u <- ii %>% mutate(Percentage = (ii[,1]/519)*100)
print(u)
It even says "cannot remove prior installation of package 'dplyr'
It's not a package loading message, it's a package installation message (which is why all the message suppression won't help). You probably shouldn't install the package every time. Try something like
if (!require("dplyr")) {
install.packages("dplyr", repos = "http://cran.us.r-project.org",
quiet = TRUE, message=FALSE))
}
If all else fails you could probably use capture.output() to make sure you had intercepted all output.
I want to check if a bunch of packages are correctly installed (to make a dockerfile crash and not silently continue).
I tried a sapply on a list of package names, and this is what happens.
Note that:
'not_available' is not installed :)
'testthat' is installed.
# to show the invisible output:

Loading required package: not_available
FALSE
Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘not_available’
So far so good, precisely as expected.
> show(require('testthat'))
TRUE
perfect...
> sapply(c('not_available', 'testthat'), require, warn.conflicts = FALSE, quietly = TRUE)
not_available testthat
FALSE FALSE
Warning messages:
1: In if (!loaded) { :
the condition has length > 1 and only the first element will be used
2: In if (!loaded) { :
the condition has length > 1 and only the first element will be used
Wuuut...
why does it warn us? And why is the output incorrect?
> sapply(c('not_available', 'testthat'), function(x) {x})
not_available testthat
"not_available" "testthat"
Oke, so sapply is not betraying me...
> sapply(c('not_available', 'testthat'), function(pkg) {require(pkg, warn.conflicts = FALSE, quietly = TRUE)})
not_available testthat
FALSE FALSE
Eeeh, now the warning is gone, but the answer.... still wrong... why?
Any clue? Expected behaviour would be a returned value with [FALSE TRUE] (relating to 'not_available' and 'testthat').
Alright, it is due to the special 'library' and 'require' behaviour to also work with unquoted values. So the following will demonstrate the failure:
pkgs <- 'testthat'
require(pkgs)
Loading required package: pkgs
Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘pkgs’
The solution is to provide 'character.only'
sapply(c('not_available', 'testthat'), require, character.only = TRUE)
not_available testthat
FALSE TRUE
works just fine.

Is the checksum not passing? Why would this be?

I am trying to install Lightgbm library in r 3.5.2.after millions of try i can do so. if anyone know how to install it?
I have try these methods to install lightgbm but always an error occur of such type.

{lgbl.dl} was originally created to make installing {lightgbm} easier, since {lightgbm} had a difficult-to-use installation process.
That package has not kept up with changes in LightGBM, and is no longer necessary to install the R package on Windows, as the original question here mentions.
{lightgbm} is now on CRAN. Run this R code to install it.
install.packages("lightgbm", repos = "https://cloud.r-project.org")
I try to highlight my R code using knit and Highlight pachages with Rstudio, but i have errors when kniting;
There's my code :
opts_chunk$set(fig.width=7, fig.height=5)
opts_knit$set(use.highlight = TRUE)
opts_knit$set(out.format = "html")
opts_chunk$set(highlight = TRUE)
opts_knit$set(...., highlight=FALSE)
render_html()
and when compiling, I have that error
Error in library(package = "parser", character.only = TRUE) :
there is no package called 'parser'
I use R 3.0
Thanks in advance
I think I have fixed this problem in the development version, and you can install it from:
install.packages('knitr', repos = 'http://www.rforge.net/', type = 'source')
