Error in .standalone_types_check_dot_call(ffi_standalone_check_number_1.0.7,

[DavidH-hub]

When I used the packages "survival" and "survminer" to draw the survival plot of BRCA patient from TCGA, it is OK before. However, suddenly, I encountered a mistake never seen before. Here is the code:

sfit <- survfit(Surv(time, event)~N_NKT_state, data=BRCA_survival) print(sfit) ggsurvplot(sfit, conf.int=T, pval=TRUE)

Error in .standalone_types_check_dot_call(ffi_standalone_check_number_1.0.7, : object 'ffi_standalone_check_number_1.0.7' not found.

Who can help me to solve this problem? Thanks!!!
