Re: [R] Removing a space from a string

The spaces may not have been VISIBLE in the Word document, but that does not mean that there wasn't anything THERE. - What happens if you open the document in Word and save it as plain text? - What happens if you open the document in Word and save it as RTF, then read that using read_rtf? -

Re: [R] Removing a space from a string

Richard In reply to your “first response”, the text was originally in a Word document and it did NOT contain the errant spaces. I used read_docx in the textreadr package to access the text. The spaces were added during that step. I am copying the maintainer of that package to see if he has

Re: [R] Removing a space from a string

The first response has to be "how did the spaces get there in the first place?" Can you fix the process that creates the data? If the process sometimes generates one extra space, are you sure it never generates two? But let's treat this purely as a regular expression problem, where if there is

1. Thanks for the nice reprex. 2. However, I thought there was still a bit of ambiguity. I interpreted your specification to mean: "any number of spaces could occur in the beginning alphabetic part of the strings before one or more digits occur followed by a '.' (a period) and then more stuff

This RegEx would do it I think: \s(?=.*\s\d*\.) Looks for space - \s Before any strings followed by space, numbers, period text <- "STR ING 01. Remainder of the string" stringr::str_replace_all(text, "\\s(?=.*\\s\\d*\\.)", "") Should do it I think! On 2020-07-28 21:34, Dennis Fisher wrote:

Re: [R] Nonlinear logistic regression fitting

Hi Rui, Thanks for your input. In my analysis, the MM model is not intended to fit continuous data but must be used within a logistic regression model of binary data. So, while useful in itself, the suggested example does not exactly apply. I appreciate your time

Hello, glm might not be the right tool for the MM model but nls is meant to fit non-linear models. And, after an on-line search, there is also package drc, function drm. I will use the data and examples in the links below. (The second gave me right, it uses nls.) #install.packages("drc")
