Was the cca function deprecated in R's ade4 package?
library(ade4)
cca(mammals, environment)
outputs
could not find function "cca"
I can't find any documentation on this error.
There is no cca function in ade4 package version 1.7-10. However, you can use cancor from base R like below
pop <- LifeCycleSavings[, 2:3]
oec <- LifeCycleSavings[, -(2:3)]
cancor(pop, oec)
Edited
Install version 1.7-4 using the following code
library(devtools)
install_version("ade4", version = "1.7-4", repos = "http://cran.us.r-project.org")
and then run
library(ade4)
May be is not available for the newest versions of the package. Nevertheless it is suggested to use cca{vegan}, which is form the vegan library.

I am attempting to perform a kappa statistic test on 2 indices I created. I've found that there are multiple packages in R that have functions for this and am trying to compare two functions: the epi.kappa() function in the epiR package and the cohen.kappa() function from the psych package.
I was able to successfully use the cohen.kappa() function with my data however, I continue to get errors when using the epi.kappa() function. My code is as follows
library(epiR)
kap.dat = matrix(c(275,78,305,154),nrow=2,byrow=TRUE)
colnames(kap.dat) = c("I1-0","I1-1")
rownames(kap.dat) = c("I2-0","I2-1")
epi.kappa(kap.dat,method="cohen",alternative= "two.sided",conf.level=0.95)
The error I get is:
Error in epi.kappa(kap.dat,method="cohen",alternative="two.sided", :
object `pO.p` not found
Check that you've got the latest version of epiR installed and update if necessary. Latest version on CRAN is 2.0.50. Type help(epi.about) once package loaded --- version of package will be shown at the bottom of the page.
I try to use the function "get_data_structure" but got an error as below.
Could anyone know how to fix it?
Thank you in advance
get_data_structure("DUR_D")
Error in data.frame(data_structure#concepts) :
trying to get slot "concepts" from an object (class "data.frame") that is not an S4 object
The problem appears to be a bug in the version of the OECD package on CRAN. If you install the development version, it works. First, close R and reopen a clean new session, then run this:
remotes::install_github("https://github.com/expersso/OECD")
library(OECD)
get_datasets()
get_data_structure("DUR_D")
remotes::install_github("https://github.com/expersso/OECD")
library(OECD)
dataset <- "DUR_D"
dstruc <- get_data_structure(dataset)
Try with get_dataset("DUR_D") i.e. without -s. as get_datasets() with -s will return a dataframe of available datasets.
It is a bug in the package OECD 0.2.5.
It works with the package version 0.2.4 which you can install from CRAN's archived package section (https://cran.r-project.org/src/contrib/Archive/OECD).
If you want to access the archived package version directly in R, use the following code:
devtools::install_version("OECD", version = "0.2.4", repos = "https://stat.ethz.ch/CRAN/")
Note that this requires the package 'devtools' to be installed.
I need your help with R not being able to run a function with rworldmap package.
When using rworldmap package in R and trying to 'joinCountryData2Map'
sPDF <- joinCountryData2Map (myframe, joinCode = "NAME", nameJoinColumn = "location", verbose = TRUE, suggestForFailedCodes = TRUE )
I get the following error:
Error in mapWithData#data <- cbind(mapWithData#data, dF[matchPosnsInUserData, :
could not find function "checkAtAssignment"
Calls: joinCountryData2Map
Execution halted
My guess is that R needs methods package, which I could not find for my R version.
Any suggestings why I 'could not find function "checkAtAssignment"'?
My R version is 3.0.2 Patched.
Using rworldmap package requires loading library(methods). I am writing it here because it was really not obvious.
Dunno what "R 3.0.2 Patched" means, but yes you are correct that somehow you don't have the methods package, which is included in the standard installation package. How about reinstalling R from the binaries or source tarball at CRAN -- that should solve your problem.
I'm using R version 3.0.2 and have installed the package tm. Previously, I also loaded a package called tm.plugin.tags. To get a measure of whether a text corpus was positive or negative I used the following approach:
library('tm')
library('tm.plugin.tags')
pos <- tm_tag_score(TermDocumentMatrix(corpus, control = list(removePunctuation = TRUE)), tm_get_tags("Positiv"))
tm.plugin.tags seems to be no longer available for R. This was based on the following classification system http://www.wjh.harvard.edu/~inquirer/homecat.htm and I'm wondering if there is any other package or approach that I can use to achieve a similar result.
I have emailed the package maintainer of tm so I will post an update here once/if I receive a response.
You can install tm.plugin.tags using the following command
install.packages("tm.plugin.tags", repos = "http://datacube.wu.ac.at", type = "source")
This installs without any problem
Thanks
Cheers
I use R version 2.15.1 (2012-06-22) and mgcv version 1.7-22
I load the following set of packages in R:
library(sqldf)
library(timeDate)
library(forecast)
library(xts)
library(tseries)
library(MASS)
library(mgcv)
It happens that I can not run a simple model (I omit the code). Even the sample code taken from the help pages:
dat = gamSim(1,n=400,dist="normal",scale=2)
b = gam(y~s(x0)+s(x1)+s(x2)+s(x3),data=dat)
gives an error:
Error in qr.qty(qrc, sm$S[[l]]) :
NA/NaN/Inf in foreign function call (arg 5)
In addition: Warning message:
In smoothCon(split$smooth.spec[[i]], data, knots, absorb.cons, scale.penalty = scale.penalty, :
number of items to replace is not a multiple of replacement length
Note that everything works fine, if I just load the package mgcv and then use the sample code right away. It also works if I just load all the packages and run the sample code. It just does not work if I
load all packages
do some file reading, sqldf statements, ts operations and some models from package forecast.
if I then apply GAM, it does not work anymore.
Apparently the variable definitions in the general environment mess up the functioning of the package.
Are there any known issues? Are there general rules that I have to obey if I load various packages? Can I write code that "disturbed" the package mgcv?
# Richard there are 2 GAM related packages: gam and mgcv. Loading both libraries at the same time usually causes a conflict.
Loading mgcv as the first package solved my problem ... strange but true.
