问题 I tried to add a part of a python code to my R Script. Unfortunately it seems that I can't use a private function for the LocalOutlierFactor in R: # Sample Data n <- 5000 n_outlier <- .05 * n set.seed(11212) inlier <- mvtnorm::rmvnorm(n, mean = c(0,0)) outlier <- mvtnorm::rmvnorm(n_outlier, mean = c(20, 20)) testdata <- rbind(inlier, outlier) smp_size <- floor(0.5 * nrow(testdata)) train_ind <- sample(seq_len(nrow(testdata)), size = smp_size) train_lof <-as.data.frame(testdata[train_ind, ])

问题 I am trying to add a python chunk in a rmarkdown document. I installed package reticulate then here is my document: ```{r, message=FALSE, warning=FALSE, echo = FALSE} library(reticulate) ``` ```{python, echo = FALSE, eval = FALSE} a=1 a #import numpy as np #import matplotlib.pyplot as plt ## evenly sampled time at 200ms intervals #t = np.arange(0., 5., 0.2) ## red dashes, blue squares and green triangles #plt.plot(t, t, 'r--', t, t**2, 'bs', t, t**3, 'g^') #plt.show() ``` However I get this

问题 I installed reticulate via Rstudio. Now i want to use conda_create() but I installed anaconda in another directory then the default. How can I change the directory in which Rstudio is searching for anaconda? Error: Unable to find conda binary. Is Anaconda installed? 回答1: The directory should be in your path. But you can check where it is like this: Sys.which("python") If you have multiple python versions (or it is not in your path), then you can specify a different location with use_python

Use reticulate to call Python script and send email

问题 I use Windows Task Scheduler to run an R Script several times a day. The script transforms some new data and adds it to an existing data file. I want to use reticulate to call a Python script that will send me an email listing how many rows of data were added, and if any errors occurred. This works correctly when I run it line by line from within RStudio. The problem is that it doesn't work when the script runs on schedule. I get the following errors: Error in py_run_file_impl(file, local,

问题 I'm trying to get Reticulate working in RMarkdown , per the setup instructions. However, I am unable to share state between separate Python cells or Python and R cells, as the docs indicate I should be able to. Here is my setup and output: Cell 1 (Setup): {r} library(reticulate) path_to_python <- "/Users/User/anaconda3/bin/python" use_python(path_to_python) knitr::knit_engines$set(python = reticulate::eng_python) py_available(initialize = TRUE) Output: [1] TRUE Cell 2 (set variable in Python)

问题 Hi this is my first stackoverflow question so sorry in advance for any mistakes. I am trying to start playing with R reticulate library.

Here is my entire code: install.packages("reticulate") library(reticulate) os <-

The first lines I run when launching my rstudio session are: library(reticulate) use_python("/usr/local/lib/python3.6/site-packages") However, when I run py_config() it shows as still using the default python 2.7 installation. This is an issue b.c I'm unable to import any modules that were installed for python3. Any idea why this isn't working? I followed documentation fairly closely. I observed that neither the technique "use_python('path')" nor the tactic of Sys.setenv(RETICULATE_PYTHON = 'path') in .RProfile worked for me (of course I am sure it must have worked for others.) In any case the
