这段代码很好用:
MATRIX_RESULT_CSV <- matrix(NA,nrow=1,ncol=5)
colnames(MATRIX_RESULT_CSV)[3:5] <- c("3", "4", "5")
colnames(MATRIX_RESULT_CSV)[1:2] <- c("1", "2")
然而,当首先填充furst列时,它会产生'dimname error':
MATRIX_RESULT_CSV <- matrix(NA,nrow=1,ncol=5)
colnames(MATRIX_RESULT_CSV)[1:2] <- c("1", "2")
colnames(MATRIX_RESULT_CSV)[3:5] <- c("3", "4", "5")
Error in `colnames<-`(`*tmp*`, value = c("1", "2")) :
length of 'dimnames' [2] not equal to array extent
我正在看下面的原因。
答案 0 :(得分:-1)
不确定其根本原因,但其中很有效:
MATRIX_RESULT_CSV <- matrix(NA,nrow=1,ncol=5)
colnames(MATRIX_RESULT_CSV) = rep(NA, ncol(MATRIX_RESULT_CSV))
colnames(MATRIX_RESULT_CSV)[1:2] = c("1","2")
