[R] long character string problem
Hi All
I am having 2 very long character strings (550chars) and I want to put them as
expressions together with c(). The problem is that I also get these
double-quotes, as seen below in 'fct'. How can I remove these double-quotes? I
tried as.name() but it did not work (because of size?). These are creating
trouble with subsequent programs, which I tested with strings that for some
reason do not have these double quotes (see very bottom).
Thanks Toby

Re: [R] long character string problem
Yes parse(text=) is what I was looking for. thanks. (I also fixed the missing
operator).
I will feed this entire expression to the deriv() function.

Re: [R] long character string problem
first of all, your expressions are not legal. For example
sqrt(B11*(X11*x1+X21*x2)^2+C11)A12*(X12*x1+X22*x2)
should be
sqrt(B11*(X11*x1+X21*x2)^2+C11)*A12*(X12*x1+X22*x2)
Here is a rewrite of your first equation that seems to present the correct
results:
> x <- expression(A11*(X11*x1+X21*x2)+1*sqrt(B11*(X11*x1+X21*x2)^2+C11)*A12*
+ (X12*x1+X22*x2)+1*sqrt(B12*(X12*x1+X22*x2)^2+C12)*A13*(X13*x1+X23*x2)+
+
-1*sqrt(B13*(X13*x1+X23*x2)^2+C13)*A14*(X14*x1+X24*x2)+-1*sqrt(B14*(X14*x1+X24*x2)^2+
+
C14)*A15*(X15*x1+X25*x2)+1*sqrt(B15*(X15*x1+X25*x2)^2+C15)*A16*(X16*x1+X26*x2)+
+
1*sqrt(B16*(X16*x1+X26*x2)^2+C16)*A17*(X17*x1+X27*x2)+1*sqrt(B17*(X17*x1+X27*x2)^2+C17)*A18*
+
(X18*x1+X28*x2)+1*sqrt(B18*(X18*x1+X28*x2)^2+C18)*A19*(X19*x1+X29*x2)+-1*
+
sqrt(B19*(X19*x1+X29*x2)^2+C19)*A110*(X110*x1+X210*x2)+1*sqrt(B110*(X110*x1+X210*x2)^2+C110))

Re: [R] long character string problem
I think you are looking for
fct <- c(parse(text=cum1),parse(text=cum2))
although you need to include operators before your A coefficients (for
example,
...C11)A12*...

[R] long character string problem
Hi All
I am having 2 very long character strings (550chars) and I want to put them as
expressions together with c(). The problem is that I also get these
double-quotes, as seen below in 'fct'. How can I remove these double-quotes? I
tried as.name() but it did not work (because of size?). These are creating
trouble with subsequent programs, which I tested with strings that for some
reason do not have these double quotes (see very bottom).
