Hi all, thanks for watching! I have a meta-analysis course that applies this juicr R package for extracting data, the full list to each lecture is found here: ru-vid.com/group/PLMDcoG6cxhI0JRfmuv3AwT9Sy0FQNMqCL
juicr package for R seems the best free semi-automatic graph digitizer program for converting plots, graphs, charts and, who knows, maybe topographic and bathymetry maps (after preprocessing) into data points. And written by an ecologist, as I learned. It's just unbelievable judging by the video
Hi Marc, I have been working for over 19 years in evidence synthesis in health care, mostly performing lit reviews and meta-analyses. I have been using web application of plot digitizer for years. I also came across digitize package in R, but never used that. I saw this video today and feel I can automate plot digitization with juicer. I am wondering if you have a peer reviewed publication on the precision of this package? And yes, I have to digitize survival curves (Kaplan Meier plots) mostly.
Okay, I just installed and ran one KM plot through it. Seems its completely unable to identify the KM plot, reading that like a scatter plot. Seems may not be useful for my purpose 😔
It's my plan this summer to update the package (with more ways to automate curves, like KM plots) and submit for publication -- sigh, so much to do, so little time 🙂
It's wonderfull, I need this for ma metanalysis! Where do you load the graphs ? I mean , I load a picture in a JPG format from a PDF article and then ?
One way is to save the image from a pdf to your desktop and then load into juicr. Alternatively, you can take a screen shot, then crop image in say MS paint, and then lead the image into juicr.
Very interesting video, I am already using juicr and I like it very much, it makes everything easier! Do you know how can I get the mean and SE with juicr from a box plot or is it a functionality that needs to be worked in the future? I just saw a research paper where the yield of a tomato is in a box plot. This is the DOI "10.1007/s13205-020-2099-4" And the boxplot is in the page 164, figure 1 top left.
It depends on what's in the boxplot. If the mean and SD are plotted, yes juicr can do this, but if it's the median and quantiles, then juicr can only extract values. You'll need to find the equation that approximates the mean and SD using the extracted values.
awesome application. many thanks for sharing 1 question. how can I "refresh" the app without closing and running again? is there a button? (apologies if such button is clearly on the app, but for some reason my laptop/monitor do not display the app window completely)
I tried to load the package as you wrote but it says Warning in install.packages : installation of package ‘juicr_0.1.tar.gz’ had non-zero exit status >...
This approach to loading juicr is appropriate if you have the package .tar file locally on your computer -- here's one way to install from a server: install.packages("juicr")
Hello Marc! I'd like to thank you for the juicr, I'm already using it and I think it's one of the best and easiest data extractors I've ever tried. However, I'm having some issues with the line chart option. When I select and click on the graph it just doesn't stop clicking and the extraction never ends. Do you know if there's anything I can do about this? As for the rest it has been perfect. Thank you!
I haven't heard of this issue yet -- I may not be able to address it right away, but perhaps you can describe a little about your workflow (e.g., what exactly you click, and then click), so I can try to replicate on my end :-)
Hello, Thanks for the Interesting video, I am using juicr and I want to extract just X and Y axis values (not pixel values) values of x-axis scale and y-axis scale. Would you please help me with that ?
click on the 'manual' page in the center column of options, and then in the 'plot-to-data calibration' section, you put the min and max values reported on the plot to convert the pixels into scaled data
@@LajeunesseLab many thanks for the reply. One more question, Can juicr package Extract the text from the plot ? (ex:- x,y-axis text, legend text etc...)
