Why does my "dtwclust" package download and load, but whenever it runs it says "could not find function "dtwclust"?

[ZZx121318]

I'm using R 4.3.0 run by Rstudio, In this process I tried to run Rstudio by giving it administrator status and by forcing (re) installing and updating the latest version of the dtwclust package (install.packages("dtwclust", repos =" http://cran.r-project.org", type="source", INSTALL_opts = '--force-reinstall')), The result is "could not find function "dtwclust", I do not understand why this is so, I urgently want someone to help me, here is my complete code, thank you!

读取数据

data <- read.csv("pig3.csv")

将长格式转化为宽格式

data_wide <- data %>%

• pivot_wider(names_from = pig_id, values_from = weight)

  定义距离函数

  dist_fun <- function(x, y) dtw(x, y)$distance

  进行聚类分析

  res <- dtwclust(data_wide,

• dist_method = dist_fun,
• k = 2:10,
• bootstrap = TRUE,
• seed = 123) Error in dtwclust(data_wide, dist_method = dist_fun, k = 2:10, bootstrap = TRUE, : could not find function "dtwclust"

  进行聚类数评估

  fviz_nbclust(res$boot_summary,

• method = "silhouette") Error in fviz_nbclust(res$boot_summary, method = "silhouette") : could not find function "fviz_nbclust"

  将聚类结果可视化

  ggplot(data_wide, aes(x = data, y = weight, color = as.factor(res$clusters))) +

• geom_line(size = 0.5) +
• facet_wrap(~pig_id, nrow = 4) +
• labs(title = "Clustering of pig weight measurements") Error in combine_vars(): ! At least one layer must contain all faceting variables: pig_id ✖ Plot is missing pig_id ✖ Layer 1 is missing pig_id Run rlang::last_trace() to see where the error occurred. Warning message: Using size aesthetic for lines was deprecated in ggplot2 3.4.0. ℹ Please use linewidth instead. This warning is displayed once every 8 hours. Call lifecycle::last_lifecycle_warnings() to see where this warning was generated.

When I upgrade the version of R to be the same as the package version, it still doesn't fix the problem. Why?

[asardaes]

Because the package doesn't include a function called dtwclust, the main function is called tsclust.

[ZZx121318]

Because the package doesn't include a function called , the main function is called .dtwclust``tsclust

Thank you very much for your reply. Then how should I modify my code?

[asardaes]

Ah I completely forgot about this. You should update your code to use the new function instead.
