from Data to Viz (external link)

from data to Viz is a new web site related to data analysis and R. Its aim is to make it easier to choose among different types of data visualisations. It looks beautiful, is easy to navigate, includes “trees” displaying a classification of visualizations and multiple individual examples with the corresponding R code.  Highly recommended!

To access the website and/or to buy the printed poster visit from Data to Viz.

 

R 3.5.0 and spaces in file paths

The R 3.5.0 update introduced a bug, at least under MS-Windows. File paths containing spaces are truncated at the first space character, leading to errors like:


Fatal error: cannot open file 'C:\Users\<user-name>\AppData\Roaming\WinEdt': No such file or directory

for a file path like 'C:\\Users\\<user-name>\\AppData\\Roaming\\WinEdt Team\\WinEdt 10\\<file-name>' or 'C:/Users/<user-name>/AppData/Roaming/WinEdt Team/WinEdt 10/<file-name>'.

This bug breaks, among other things, the ‘RManager’ extension of the editor WinEdt. I would expect this to cause various other surprising errors after upgrading to R 3.5.0.

This bug is already corrected in the patched version of R 3.5.0 available through CRAN. For Windows, the most recent patched R version can be downloaded from https://cran.r-project.org/bin/windows/base/rpatched.html and installed as usual.

ooacquire 0.1.5

Improvements aiming at continuing the expansion of the support of different Ocean Optics spectrometers and of  additional calibration methods.
