Pubmed API returns less results than web interface

Asked 2021-Apr-13 at 14:33

I'm trying to access Pubmed results via R using their API, but I consistently get fewer results than what the same query achieves when used with the web interface. By digging in the output I noticed that the problem lays in a different query translation between the two access methods.

I am using the rentrez package, but the results I get are the same also with other related rpackages, so I guess it's related to the API itself.

here's the code to reproduce the results:

Not sure if you still need this now. Just in case someone else has the same problem. I had the same issue as you did and I found something might be useful from a GitHub issue. It seems that the API service needs to be updated to match the new web service, but it's been a year now and still no promising announcement has been made by the official. An alternative is provided by the easyPubMed author. Hope this is what you were looking for.

Transform 3D Lidar-Points from cartesian coordinate-system to spherical coordinate-system and a stereographic projection

Asked 2020-Sep-25 at 13:35

I'm working on my master thesis to simulate hemispherical photographs from Lidar-Data. So my main goal is to project 3D Points (X,Y,Z) which are in a cartesian coordinate system to a stereographic projection (See picture 1, from: here). The coordinate-system of my Pointcloud is transformed so that the center point is located a (0,0,0) and all z-values are positive.

I'm coding in RStudio and I first tried to achieve a spherical projection of the Pointcloud by using the formula for cartesian to spherical coordinates listed on wikipedia.

Introduce a Rlist in Python using rpy2

Asked 2020-Jun-21 at 12:36

I am controlling R trough Python by rpy2 package. Everything works fine except when I have to introduce some function arguments throug a Rlist. Rlists are defined by the same keyword than Python: list; but its content it's very different. Since Python believes I am creating a Python list, instead of a Rlist, an error is always shown. I am using rpy2 to control WaveleComp R package.

rpy2.rinterface.initr is used to initialize the embedded R, and you will not need to worry about it if using the rpy2.robjects interface.

ListVector is an rpy2 class, only visible from the Python side: https://rpy2.github.io/doc/v3.3.x/html/vector.html#rpy2.robjects.vectors.ListVector

Well, tbh, you've done no research and want folks to give you special treatment, which is fine, but not going to get you very far on SO. There are tons of questions on SO for RCurl and loads of web sites that specifically talk about how to use it in the context of FTP downloads.

But, the following might help someone who has done some research and is truly stuck, plus will also show how to use the more modern curl and httr packages.

On top of some RCurl tutoring you kinda also expected folks to register for that site (since one might have assumed there were idiosyncrasies in that site's FTP server that were causing issues with RCurl…I mean, we have no context so that's as valid an assumption as any).

Put these in ~/.Renviron and restart your R session:

You evidently took away (the useful value for) PATH by providing your own environment. If you want to be like the shell, make only the minimum necessary changes to the environment you inherit.
