...ular function, then make use of it later, perhaps in a different function, without necessarily having to move it around in argument lists. In the C community, it would be called a "global" variable. Question 1: Is this practical at all in the R language? Suppose the variable is called x23. I want to assign a value to it, then use it later. Seemingly, there are two cases: Case I is if the variable is given its value at the top level. Case II is if it is given its value inside a user-defined function. That I do not know how to do. Example: func1 <- function (){ x23 <- 2.6...

Dear all, I have encountered a problem when perform stepwise regression. The dataset have more 9 independent variables, but 7 observation. In R, before performing stepwise, a lm object should be given. fm <- lm(y ~ X1 + X2 + X3 + X11 + X22 + X33 + X12 + X13 + X23) However, summary(fm) will give: Residual standard error: NaN on 0 degrees of freedom Multiple R-Squared: 1, Adjusted R-squared: NaN F-statistic: NaN on 6 and 0 DF, p-value: NA In this situation, step() or stepAIC() will not give any useful information. I don't know why SAS...

Hi, Having a vector x of float type without any assumption of its distribution (mean, variance etc), how to generate another vector that is correlated with x? Extensibility: how to simulate more than two correlated vectors (again float type and no preference for their distribution and without having vector x)? Cheers, Carol

I have a dataset that is basically structureless. Its dimension varies from row to row and sep(s) are a mixture of tab and semi colon (;) and example is HEADER1 HEADER2 HEADER3 HEADER3 A1 B1 C1 X11;X12;X13 A2 B2 C2 X21;X22;X23;X24;X25 A3 B3 C3 A4 B4 C4 X41;X42;X43 A5 B5 C5 X51 etc., say. Note that a blank under HEADER3 corresponds to non occurance and all semi colon (;) delimited variables are under HEADER3. These values run into tens of thousands. I want to give som...

Hola, gracias por la respuesta, No me funcionó debido a que los nombres de las variables no están seriadas, es decir, los nombres de las variables son del tipo: x23 x25 x30, x301 x320, x80. Entonces me da este error: Error in eval(predvars, data, env) : object 'pot24' not found. Debido a que pot24 no existe, ya que de pot23 se brinca a pot30. En Stata es algo muy simple de hacer, solo tengo que especificar gl indepvars "x23-x80" y ya. En R n...
