Just read this from an influencer I follow on LinkedIn: Deep domain expertise plus alien-level technical skills equals lots of interesting and rewarding work to do.

People think R is just for stats. But it also shines in many areas:
✔️ Pulling and cleaning data from Google Sheets (googlesheets4), Qualtrics surveys (qualtRics), Census Bureau APIs (tidycensus), and transforming with dplyr + tidyr;

I was analyzing the 50-day vs. 200-day moving average using #Python when I encountered some errors. I turned to #AI for quick solutions. I could not be more excited about all what is available at my fingertips in mini-seconds. #Copilot #GoogleColab

$SPY MACD hitting elevated zones reminds me of previous cycles 📊 When we see hits around 1.5 like July 3rd, it's worth noting the historical context - similar extreme readings often preceded significant corrections. Not a sell signal, but worth watching for divergence! #SPY #MACD #TechnicalAnalysis

Now a similar upward momentum to Mar 2025 is emerging, though that surge in March was followed by a sharp drop in April. #MACD is typically mean-reverting—extreme values may signal reversals. How do you think this July trend will play out? Note: No Investment Advice #SPY #DataViz #Trading #RStats

📊Just plotted $SPY data with moving averages. The blue line (50-day) crossed above the red line - LONG bullish signal! From ~$380 to $620 since 2023. The chart doesn't predict the future though. What do you think will happen next?🐃or 🐻

I just ran a word frequency analysis on some Reddit posts scraped from #WallStreetBets using #Rstats. It looks like discussions about calls vs. puts have been hot. Any other types of analyses do you think might be useful? #TradingTips #Trading #OptionsTrading

Everyone was talking about the game. I thought it might be fun to see how people talk about the #Superbowl at #BlueSky. With some tweaks to the text data scraped from BlueSky using #RStudio, I was able to draw a WordCloud that predicts the winner of the #SuperBowl game. #RStats #TextAnalysis
