knit2wp error. Doesn't recognize username or password

Question

I'm using the knitr package to post an .Rmd file to wordpress. First time I'm working this type of project and am having the following error/issue. Can anyone help identify the issue. Have done a number of Google searches but haven't seem similar issues. Also tried to use the newPost function for this task but that was unfruitful.

if (!require('RWordPress'))
  install.packages('RWordPress', repos = 'http://www.omegahat.org/R', type = 'source')
library(RWordPress)
options(WordPressLogin = c(username = "*****"),
        WordPressURL = "https://mathewanalytics.com/xmlrpc.php")

library(knitr)
knit2wp("Logistic_Regression_Document.Rmd", 
        title = "Evaluation Logistic Regression in R", 
        shortcode=TRUE, publish=FALSE )


List of 4
 $ results: chr "hide"
 $ message: logi FALSE
 $ warning: logi FALSE
 $ eval   : logi FALSE

  |.................................................................| 100%
  ordinary text without R code


output file: Logistic_Regression_Document.md

Error in getOption("WordpressLogin", stop("need a login and password")) : 
  need a login and password
In addition: Warning messages:
1: In Ops.factor(1, obs) : '-' not meaningful for factors
2: In Ops.factor(1, obs) : '-' not meaningful for factors
3: In Ops.factor(1, y) : '-' not meaningful for factors

Answer 1

I had this problem too, and it turned out to be a problem with the variable names.

You are setting: (note the capital P)

WordPressLogin = c(username = "*****")

But the function is throwing this error:

Error in getOption("WordpressLogin", stop("need a login and password"))

So if you set the right variables:

options(WordpressLogin = c(username = "*****"),
         WordpressURL = "https://mathewanalytics.com/xmlrpc.php")

Then you should be ok.
