Re: [R] dealing with a messy dataset

Is this a fixed width format? If so, read.fwf() in base, or read_fwf() in the readr package will solve the problem. You may need to trim trailing spaces though. B. > On Oct 5, 2017, at 10:12 AM, jean-philippe > wrote: > > dear R-users, > > > I am

Re: [R] A question about for loop

There are many ways to get the output you want, so your question is ill defined. But it is easy to see where your code goes wrong. And it should be easy for you to fix it. If you subset a vector with the '[' operator, this is like putting a vector of indices "into" the square brackets. So, to

You need a stemming algorithm. See here: https://cran.r-project.org/web/views/NaturalLanguageProcessing.html Myself, I've had good experience with Rstem. B. > On Jul 31, 2017, at 4:47 PM, Riaan Van Der Walt > wrote: > > I am new to R. > Busy with Text

Re: [R] Please help(urgent) - How to simulate transactional data for reliability/survival analysis

In principle what you need to do is the following: - break down the time you wish to simulate into intervals. - for each interval, and each failure mode, determine the probability of an event. Determining the probability is the fun part, where you make your domain knowledge explicit and

Run it through a loop. I assume the cell contents is NA (Not Available). Test for it with is.na(). Whenever that returns TRUE, replace the NA value with the value from the previous row. Cheers, B. > On Jun 24, 2017, at 1:49 PM, Christophe Elek > wrote: > > Hello

If I understand you correctly what you are really asking is how to embed quotes in a string so that it can be parse()'d as an expression. The answer would be: escape the quotes. R > myOptions <- "Hello" R > eval(parse(text = paste( "print(", myOptions, ")" ))) Error in print(Hello) : object
