Hello, I'd like to generate a filled step-function in R as you can see in the attachement (image is generated by grapher, but I need a freely available alternative). The problem is, that I don't know, how to fill it up. My code right now looks like this: pH <- c(0,6.1,6.1,6.3,6.6,7.3,0) Tiefe <- c(0,0,10,40,80,120,10) plot(pH,Tiefe,type="s",main="Tiefenfunktion pH",ylim=c(120,0),xli...

I have very large data sets given in a format similar to d below. Converting these to a data frame is a bottleneck in my application. My fastest version is given below, but it look clumsy to me. Any ideas?

Dear friends - merry Christmas and thanks a lot for much help during the year! In the example below I fail to understand how the calculated value pH is represented in a simple plot - also included. The calculations are useful in practice and likely to be right in principle but I cannot see how this occurs: why a calculated value of 7.4 known as numeric is not simply plotted as such. It happened on Windows both 7 and 10 with R version 3.4.1...

Hi Sergei, "addRuntimeCheck" inserts code that checks that two or more arrays are disjoint. I looked at the code and it looks fine. We generate PHIs in the order that they appear in a vector. The values are inserted in 'canVectorizeMemory', which also looks fine. Please let me know if you think I missed something.

Nadav, As I peel this onion, it looks like you might know something about InnerLoopVectorizer::addRuntimeCheck. What does it do, and can it be causing the below described issue? Could resuming somehow (indeterministically) switch the order of PHIs in the original code? Thanks a lot.

Dear all, My name is Maria Lathouri and I am currently doing a PhD at Imperial College of London about time series of environmental variables in surface waters. I am trying to do some time plots with R but it seems that it is not working. The problem is that the time is not regular, for example, a small dataset can be seen below: Date pH 1/02/1998...

Hi, I'm sure this should be simple but I can't figure it out! I want to get the median survival calculated by the survfit function and use the value rather than just be able to print it.

...that the given loop ends up vectorized with enough difference to cause bad things later on, but I have not found the exact cause yet. To continue with my work I'll have to simply turn off vectorization for now, but I will come back and investigate. Again, there is some indeterminism in order of PHIs processing somewhere.

Thanks a lot - formatting the ordinate as ylim=c(4,10) before plotting pH also removed the problem, and options(digits=10) confirmed that pH was not all exactly 7.4 - as I knew. Still I wonder just why R chooses to plot(ATOT,pH) as shown with repeated "7.4" instead of some more detailed representation. Thanks a gain and happy New Year! Troels Den 26-12-20...
