Strange R squared, possible error
k=lm(y~x)
summary(k)
returns R^2=0.9994
lm(y~x) is supposed to find coef. a anb b in y=a*x+b
l=lm(y~x+0)
summary(l)
returns R^2=0.9998
lm(y~x+0) is supposed to find coef. a in y=a*x+b while setting b=0
The question is why do I get better R^2, when it should be otherwise?
Im sorry to use the word "MS exel" here, but I verified it in exel and it
gives:
R^2=0.9994 when y=a*x+b is used

random typing over text
Dear R,
When I'm writing script I probably hit accidently some hot key and then the
text in script is being overwritten
by subsequent typing. Please what is the hot key or how can I disable it?

Hello R,
I have data in txt file of n columns like this:
x y1 .....yn
1 100
2 50
3 10
4 200
5 20
I need to find coordinates for each maxima e.g.: [x,y1],[x,y2]...[x,yn]
a=read.table()
attach(a)
b=y1<-x
max(b) returns only value of y but no corresponding x value
