I am a chemical engineer by training. Is there not something like law of
corresponding states in numerical analysis?

Dear R-experts,
I am relatively new to R. Please help me in converting a dataframe into a
numeric and then creating a new dataframe.
R-code attached:
my_xtrain=read.table("./train/X_train.txt")
my_xtest=read.table("./test/X_test.txt")
my_merge_data=merge(my_xtrain,my_xtest,all=TRUE)

N.b. There's also a missing "}" and totally messed up formatting :-(

Eva and Professor Peng,
I spent many hours on Programming Assignment 1, however I was unable to get it
right. I found it most useful and think others should work at it too!
Please do send me your work now that the deadline is over. Or you could tell me
your Github account so that I could fork i

Hi,
I have 2 queries:
1. What function to use to read all the files in a directory to a vector in R
code?
2. What function to use to coerce character string into numeric?
As a help to others, I figured out to use setwd("C:/") to set working
directory!
