Hi list Recently, when starting up RStudio, the following warning is being displayed: "Error in tools:::httpdPort <= 0L : comparison (4) is possible only for atomic and list types" I think that this is specific to RStudio because starting R in...

Hi list I've signed up for a Coursera course on exploratory data analysis, and the recommendation is to update to R base 3.1.1. I'm currently on 3.0.2. If I do upgrade, what is the...

Hi list Using the tm package, part of the pre-processing work is to remove words, etc. from the corpus. I wish to remove people's names and also their initials which are peppered throughout the corpus. But, because some...

Hi list Although this query applies specifically to the tm package, perhaps it's something that others might be able to lend a thought to. Using tm to do some initial text mining, I want to include an external (to...

Hi list Can someone help me debug the following please: Having downloaded and installed the bioconductor packages and Rgraphviz, I am attempting to plot a network graph showing the relation among chosen words in the corpus of text data. I...

Brilliant Jim - that does the trick!! I guess then that the semi-colon rule works for any program or function that is being written on one line? Any reason why when writing this out in the RStudio source editor no...

Hi Jim The name's come up on my radar, but that's about it. I'll look into it. Thanks for the reference. All the best S On 10/04/15 23:36, Jim Lemon wrote: > Hi Sun, > No...

Hi list Closing this one off myself, this is what I did: The error seems to concern the update of tm to version 0.6: the conversion to lower case text should now be: > docs <- tm_map(docs, content_transformer...

Hi list I've been working my way through a tutorial on text mining ( http://onepager.togaware.com/TextMiningO.pdf ) and all was well until I came across this problem using tm (text miner): ++++++++++code+++++++++++++++++++ > docs <- tm_map(docs, content...

Hi Aurora I wonder if the problem you are having concerns the GCC (GNU c) compiler rather than R itself? I know it doesn't help you, but using the exact same rig as yourself, rmarkdown installed successful after pulling...

Thanks Jim. I thought that I was passing a vector, not realising I had converted this to a list object. I haven't come across the scan() function so far, so this is good to know. Good explanation - I'll...
