[R] post tweets with media attachment - and with retirement of rtweet

All - I run an automated script that pulls in some market data, makes some charts, and posts them to twitter. A couple of them per day, and then once per month there's a little flurry around the CPI report. For a while rtweet() worked great. Then v2 happened and Oauth2.0. The package broke, wa

Always amazes me how many ways there are to do these things, none of which I was able to find myself. Thanks! I think the key here was ‘pmin,’ which I didn’t know before. Michael Ashton, CFA Managing Principal Enduring Investments LLC W: 973.457.4602 C: 551.655.8006 Schedule a Call: https

with Rexcel? I've updated Rexcel to 3.2.16 but it made no difference. Any suggestions of what to try will be warmly entertained! Thanks, Mike Michael Ashton, CFA Managing Principal Enduring Investments LLC W: 973.457.4602 C: 551.655.8006 [[alternative HTML version deleted]]

Thans Dan. It seems that it may be an issue with 3.4.3...I'm going to attempt a patch this weekend. The code works fine from the command line in 3.2.5! Michael Ashton, CFA Managing Principal Enduring Investments LLC W: 973.457.4602 C: 551.655.8006 -Original Message- From: D

Re: [R] command line fails

Fascinating. The script runs fine in 3.2.5, but won't run in 3.4.3 even with ALL lines commented out. I have no idea what that means. I can't imagine I found a 3.4.3 bug no one knows about. Michael Ashton, CFA Managing Principal Enduring Investments LLC W: 973.457.4602 C: 55

I am having a hard time with 'next'. I come from the "sloppy" school that learned BASIC with Goto. Conceptually next seems pretty straightforward. I just can't get it to work correctly in my code. Here's a stripped down version: WhichRunNow<-"Daily" Cnums=c(0,1,"2b3") Cpers=c("Daily","Daily","W

[R] getting a subset corresponding to a list element

I'm not sure how to ask this with the proper terminology, but here goes: The BDH() function in RBLPAPI returns, for a list of symbols (e.g., 'SPX Index','RIY Index','IBM Equity') a list of closing prices. The problem is that the result is not a matrix or a dataframe, but a list. So, if I run th
