Function "funcit" not work

[Jo1984]

Before work inside the library funcy (especially the function funcit), I loaded the following packages: flexclust, fda, wavethresh, kernlab, modeltools, car, carData, fields, calibrate, sm, MASS.
At the end I loaded the package funcy.
I try to run the example (find inside the help):

set.seed(2804)
ds<-samplesFuncy(obsNr=50,k=4,timeNr=8,reg=TRUE)
res<-funcit(data=data(ds),clusters=Cluster(ds),methods=c(1,2,3),seed=2404,k=4)

After the last script, appear this error message: "Error in command 'create.bspline.irregular(c(time[1], time[m]), nbasis = nbasis, ': failed to find function 'create.bspline.irregular' ". I check this function and it is inside the fda package (and it was installed).
I do not undesratnd were is the mistake. I try the other examples and all give me the same error.

We probably need more information.

FAQ: What's a reproducible example (`reprex`) and how do I create one?

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution. What's in a Reproducible Example? Parts of a reproducible example: background information - Describe what you are trying to do. What have you already done? complete set up - include any library() calls and data to reproduce your issue. data for a reprex: Here's a discussion on setting up data for a reprex make it run - include the minimal code required to reproduce your error on the data…

Which information do you need? I try the example that I found in help(funcit) and it did not work.

@Jo1984

Which information do you need?

I am not sure as I do not have funcy or most of the rest of those packages installed but before anything else try shutting down RStudio and R and restart.

Then try

library(funcy)
set.seed(2804)
ds<-samplesFuncy(obsNr=50,k=4,timeNr=8,reg=TRUE)
res<-funcit(data=data(ds),clusters=Cluster(ds),methods=c(1,2,3),seed=2404,k=4)

One of those other libraries may be masking something. The function create.bspline.irregular seems to be from *fda .

Otherwise, let's start with your OS, version of R & of RStudio and the output of sessionInfo()

The problem persist.

You comment is not constructive as you provide no actionable feedback... but regardless this issue is almost certainly because this ecosystem of packages is perhaps not actively maintained and seem somewhat disordered. I was able to find a particular combination of the core packages that seemed to 'work'.
I would strongly advise you not to do any significant work with these tools without also using a combination of renv and git tracking, to record and document the library dependencies should you want to revisit work down the road.

#setup
library(renv)
install("funcy@1.0.0")  # 1.0.1 was removed from CRAN
install("Funclustering@1.0.2")
install("fda@2.4.8")

#test
library(funcy)
library(fda)
library(Funclustering)

set.seed(2804)
ds <- sampleFuncy(obsNr=50, k=4, timeNr=8, reg=TRUE)

##Cluster the functions with all available methods. 
res <- funcit(data=Data(ds), clusters=Cluster(ds),
              methods=c(1,2,3,4), seed=2404,
              k=4)
