Please send reproducible code when you report problems.
I am unable to reproduce your problem. It seems to work just fine.
dat - read.table(e:/temp/crrdata.txt, sep=\t, header=TRUE)
names(dat)
[1] x1 x2 fstatus ftime
dim(dat)
[1] 198 4
cov=cbind(dat$x1,dat$x2)
z - crr(dat$ftime, dat$fstatus, cov)
z
convergence: TRUE
coefficients:
[1] 0.360900 -0.002484
standard errors:
[1] 0.23180 0.03413
two-sided p-values:
[1] 0.12 0.94
So, what is your problem?
Also, make sure that you understand what you are doing with competing risks
analysis. It seems like you do not have any censoring, i.e. all the subjects
are failing from one of three causes. Read the documentation of ?crr carefully.

Dear all,
I am trying to use the crr function in the cmprsk
package version 2.2 to analyse 198 observations.I have receive the
error in solve.default.
Can anyone give me some
insights into where the problem is?
Thanks
here is my script :
cov=cbind(x1,x2)
z-crr(ftime,fstatus,cov))
and data file:
