防止R在“中”内四舍五入;表达方式;功能

防止R在“中”内四舍五入;表达方式;功能,r,R,我需要在绘图中精确显示98.0,但很不幸,R只显示98+-2.3Ω text(0.03,8, expression(Rx == 98.0 +- 2.3* phantom(x)*Omega), cex = 1.5, col = "red") 多谢各位 plot( x = 1:10, y = 1:10 ) text(4,8, expression( Rx == '98.0' %+-% 2.3 *phantom(x)* Omega ), cex = 1.5

  text(0.03,8,  expression(Rx ==    98.0   +-  2.3* phantom(x)*Omega), cex = 1.5, col = "red")
多谢各位

plot( x = 1:10, y = 1:10 )
text(4,8,
     expression( Rx == '98.0'   %+-%  2.3 *phantom(x)* Omega ),
     cex = 1.5, col = "red")
